Dear Welder Series… Mustang II for 1947 Chevy 3800?

Dear Welder Series…
I am looking for a mustang 2 front crossmember that I can weld my self. I see you have one for a model A but I need one for a 47 Chevy 3800. Is it the same one or do you offer a different one for different vehicles?
Thanks,
Derek

Dear Derek…
The 3800 truck is the 1 ton version, as I’m sure you know. I believe, but don’t know for sure, that the frame is the same width as the 1/2 ton truck. If this is true, the 56″ kits are the right width. Assembly and installation info is below the description of the kits at http://www.welderseries.com/blog/online-store/ws14540/ and

The videos will help you see what is involved in putting the kit in your frame.

Thanks for looking at Welder Series parts.

Dear Welder Series… Mustang II: installed frame height?

Dear Welder Series…
Hi I’m building a custom frame I want to run a Mustang ll I like how you sell them and I plan on buying one from you my question is if running air springs and a 24 inch diameter wheel how high should the frame rails be from the ground and with 6 inches of ground clearance I want the rockers of the car to sit on the ground, like I said its custom so the frame rails can be placed anywhere. Also do you have a laser cutter or are you farming out your cuts, the reason I’m asking I have some custom shaped frame rail ideas and I like the idea of cutting and welding the shapes I want, would custom cuts be something you would be interested in doing for me? Thanks for any help and could I bother you for a catalog? I can’t see any of your products on the web site the pics are black or digital mess ..

Tom

Dear Tom…
Tom, the frame height should be mocked up once you have the wheels and tires you will use. Then our install sheets walk you through how to cut the crossmember and upper towers so the frame will be where you want it with weight on the tires.

We work with a local laser cutter who understands what we are looking for in street rod products. We do custom work regularly and would be happy to quote on your drawings or sketches.

We’re working on the web store images… sorry for the inconvenience.

Dear Welder Series… MII & rear four link dimension questions…

Dear Welder Series…
Hi there

I’m working on figuring out ride height and road clearance for my 51 Chevy if I use your MII set up and have a few questions, hoping you can assist.

1. For your MII front crossmember, what is the distance from the underside of the chevy frame to the bottom of the crossmember and what should a reasonable /safe clearance below the crossmember to the road be?

2. What is the distance from the spindle centerline to the underside of the crossmember. (assuming 2” drop spindle)

I am trying to determine from this what size wheel/tire size should be.

3. For the rear suspension, triangulated 4 link kit or individual pieces, can you please clarify the dimensions of your bars so I can figure out where they will attach to my frame?.

Your drawing indicates the lower bar should be 27-1/8 from the axle centerline but you list a 27-7/8 bar and then 23-1/8 bar and nothing in between.

Are dimensions nominally center to center on the bushings? Or center of bushing to edge of notch?

4. The upper bar should attach about 15 from the axle centerline according to your drawing so I want to see where that would end up mounting on the axle.

Can you clarify roughly what angle in plan view the upper bars are relative to the axle or roughly what length the upper bars are so I can figure out where they will sit and if that is similar to your drawing showing the bars 2-1/8 above the axle centerline?

Thanks very much for your assistance.!!

Steve

Dear Steve…
Thanks for looking at Welder Series parts for your project, Steve.

I suggest you choose the tire size that you feel is best for your project, rather than work from ground clearance up. Our crossmember can be notched to accommodate the ride height you want with the tire size you choose.

I’m going to duck the ground clearance question… This depends on the roads you travel as well as possible laws in your area. NSRA has a practical suggestion with their scrub line definition. This is defined at http://www.dmv.state.pa.us/pdotforms/pub_45/appendix.pdf . Some areas say the line should be drawn from wheel rim to wheel rim and no suspension component should below that line.

With a 2″ dropped spindle, it is 7-1/4″ from spindle c/l to the bottom of our crossmember.

The dimensions on the triangulated rear 4-link installation sheets are correct. The assumption is that you know where the axle centerline is but don’t know where our axle bracket locates the urethane bushing. The bar length is from the center of the urethane bushing tube to the threaded end of the bar. The adjuster is not included in this length. Add 1-3/4″ for the large bushing adjuster. Note that the lower bar for the triangulated kit is the 23-1/8″ bar. (The 27-7/8″ bar is 7/8″ diameter and is used in our universal rear Panhard kit and the hiboy front 4-link kit.)

The frame brackets for the upper bars will likely have to be trimmed to the angle suited to your frame width and rear axle.

Thanks for these questions. I hope this info, and the install sheets online help you.

Dear Welder Series… Mustang II crossmember dimensions?

Dear Welder Series…
Interested in your mustang II crossmember with coil overs. How much does the crossmember weigh and how wide is it outside to outside at the lower control arm mount? Thanks. Steve.

Dear Steve…
The 56″ crossmember kit with the upper arm brackets and coil-over mounts weighs 32 lbs.

The two crossmember pieces and the plates that run from the top of the crossmember to the inside of the frame weigh 19 lbs.

The lower control arm holes are on 22-1/4″ centers. If the center line is extended each way, the crossmember dimension is 25-5/16″.

I hope this helps.

Dear Welder Series… Mustang II in a ’65 F100?

Dear Welder Series…
Not sure if this is where you send in a question for “Dear Welder Series”, but I’ll ask anyways.

I have a 65 ford F-100. I’d like to change out the front suspension to, of course, MII. The problem is that I have a Twin I-Beam set up with no control arms….if I were to get your MII crossmember, how would I know what control arms, spindles, brake set-up, what size coilovers to get? I’m just starting the research and I’m a little confused. Can you lead me in the direction here.

Thanks,

Drew

Dear Drew…
Glad you wrote, Drew. This is exactly the kind of question we deal with at DWS.

Your truck would use our 60″ Mustang II kit, Drew. Other front end parts can be used from a “dead” Mustang II (1974-78) or 1974 – 80 Pinto. The hot rod aftermarket has everything brand new, too. Just get parts for 1974-78 Mustang II and you’ll have the right things. The 1979-92 T-Bird power rack is a good choice if you plan on power steering. Stock or dropped spindles can be used with our kit.

Welder Series has a disc brake kit, http://www.welderseries.com/blog/online-store/mustang-ii-brake-kit-for-granada-rotors/. Coil-overs with a ride height of 12 – 13″ will be good for the MII coil-over kit.

I hope this helps. You will likely have more questions as your research continues. Please ask us. We want to help you have fun with this project.

Dear Welder Series… Mustang II for 1937 Dodge Business Coupe?

Dear Welder Series…
Hello, I am looking for a complete IFS front end kit for my 1937 Dodge D5 Business Coupe. Do you offer such a kit? If not, do you know who may?

Thanks
Kelsey

Dear Kelsey…
Kelsey, thanks for writing. Our 56″ kit would be the one to use. Welder Series sells the crossmember and upper towers only, not a “hub-to-hub” kit.

Some of our dealers offer complete packages. http://www.welderseries.com/blog/dealers-builders/

I hope we can help with your project.

Dear Welder Series… Mustang II for a ’64 Volvo?

Dear Welder Series…
I’m looking to do a 56″ wide MII on a ’64 Volvo PV 544. The frame stubs are somewhat hat shaped like a 40′s Chevy. The main rails are 21-3/4″ inside above the hat and are 2-7/8″ wide.

The hat is 20-1/8″ inside and 29-1/8″ outside.

At desired ride height the bottom of the hat is 14-1/4″ above the ground. The lower a-arm pivot is at 8-5/8″ above the ground and the spindle centerline is 11-1/2″ above the ground.

I haven’t found any diagrams that give the same sort of info for a MII. Is your standard kit any where near being able to fit in the confines of the Volvo frame rails. I’m a competent fabricator so I can change the rail tops as may be required. The car will be getting 10″ rear tires and widened fenders so an increased track width in the front can be accommodated by fender mods there too.

Thanks for any info you can supply along with a price including shipping.

Charlie

Dear Charlie…
Thanks for this note, Charlie.

Here is some dimensional info about our MII crossmember:
The 56″ crossmember is 30″ wide outside the “wings” on each end. The crossmember can weld to the bottom and the outside of the frame rail, when this is practical. The top of the crossmember is 3″ higher than spindle c/l. The bottom of your frame will pretty much be sitting on top of the crossmember “wings”. At the top of the wings, the dimension from inside corner to corner is just over 25″.

The spring towers will not work easily with this frame configuration, because the upper arm cross shaft will be lower than the top of the
frame rail and the cross shafts will be on 29-1/2″ centers (approx). The frame o.d. is too wide for the arms.

It might be easier to make new frame rails from the firewall forward, or at least in the crossmember/spring tower area. The WS14340 kit can be notched so the frame will sit at the ride height you want. Could you design the frame section so the bottom of the frame is about spindle
height and the frame O.D. is about 30″? I hope this helps. If there are other dimensions you need, please get in touch.

Paul Horton.

Thanks Paul,

Doing some measuring today I realize that I’ll have to modify the upper portion of my frame. That’s really not a problem I think. The good part is that it looks like I can add a flange to each side of the MII crossmember to facilitate bolting the crossmember in place while determining ride height.

I will order a WS14340 kit in the next day or so. I appreciated your help – very clear.

Dear Welder Series… Mustang II for Sunbeam Alpine?

Dear Welder Series…
I have a 60 Sunbeam Alpine. It has a front track width of 51”. Can you supply a mustang II kit to fit?

Scott

Dear Scott…
Thanks for asking, Scott. The easiest way for me to answer this is to give you the link to our blog. Several people have wondered about narrow kits… http://www.welderseries.com/blog/?s=narrow+mustang+ii

The Alpine will be a neat project.

Dear Welder Series… Mustang II for a bug?

Dear Welder Series…
I am building a prostreet chassis VW bug the front frame rails are 25.5″ outside to outside 2×3 rectangle need to get the proper width crossmember don’t know what to order.

Dear Writer…
Our crossmembers are ordered by track width. We call track width the distance from the wheel mounting surface of one rotor to the wheel mounting surface of the opposite rotor. In “real life” this dimension varies with Mustang II installations, depending on the brakes being used. A stock Mustang II (1974 – 78) has a track width of 56-1/2″. If stock, 4-bolt MII rotors are used on our 56″ kit, the track width would be 56-1/2″.

The frame should be at least 26″ O.D. to use our 56″ kit. If you plan to have a track width less than 56-1/2, the crossmember can be narrowed and the minimum frame width can be less by the amount taken out of the crossmember.

If you will use the 56-1/2″ track width, the frame should be made wider, at least in the crossmember area.

All of this is to say the 56″ crossmember is probably the one to order.

Thanks for looking at Welder Series parts.
