Dear Welder Series… 1949 International kb1 Mustang II

Dear Welder Series…
I have a 1949 international kb1. I would like to use coil springs and the mustang 2. I think it would take the 60 inch track. Is this correct? What would be the total cost shipped to Winnipeg? Do you offer welding of the basic member? Thanks

Dear Paul,
Paul, There are 2 frames for KB1’s, according to my info, 28” and 30” outside width. With either of these frames, I’d widen the frame outside dimension by adding tubing so the 60” kit has more frame surface to weld to. Read through the installation sheets at and I think you’ll see what I mean. (30” frame outside doesn’t give any surface on top of the frame for the upper tower to weld to in the 60″ kit.)

Here is a link to the web store page for the Mustang II:

There are other parts there that you might need, too, and some videos.

The 60-1/2” kit, welded, including freight and sales tax would total C$346.50.  (That’s Canadian Dollars…)

Thanks for looking at Welder Series parts for your project.

Dear Welder Series… coil over specs?

Dear Welder Series…
I just purchased a 1950 Chevy 3100 truck where the seller installed WS21906 in the front and WS318500 in the rear of the original frame. I was hoping you could suggested an affordable set of coil overs that would work with this setup. Unfortunately I have no idea as to what I should be looking for in terms of the stroke, lengths, dampening, etc.. Thank you.


Dear Yuchol…
Congratulations on your new project! These are great looking trucks.

I suggest blocking the truck at ride height to establish coil-over ride height.

If the upper mounts for the front shocks have been installed, the ride height for the coil-overs will be the center-to-center distance between the mounting holes on the lower arms and the brackets. If the frame plates have not been installed, go to, pages 2 and 13 will help.

If the rear crossmember has been installed to mount the top of the coil-overs, the truck’s ride height you have chosen with the mock-up will give you the coil-over ride height. If there isn’t yet a place to mount the top of the coil-over, please consider the crossmember

The coil-over mounting angle is discussed at . The coil-over ride height can be determined when you mock up the crossmember and mounting points.

Regarding the coil-over stroke, generally longer is better as it will offer more suspension travel. Other factors or interference points also come into play. Viking, RideTech and other North American companies make quality coil-overs.

I hope this helps with your decisions.

Dear Welder Series…
Thank you so much!


Dear Welder Series… thru frame tie rod end mount on the rear?

Dear Welder Series…
I have a question concerning your thru frame hair pin mounts. Have you ever seen them used on rear radius rods with a single front mount?

Dear Steve…
Hi, Steve.  I haven’t seen them used in that type of rear suspension.  But I believe our through-frame mount would be stronger than any other tie rod end mount.  The amount of support for the tapered stud, from the large area of the tapered stud to the button head is 2”, so actually wider than for any tapered hole bracket.

I hope this answers your question, but please expand on it if I missed your point.

Thanks for looking at Welder Series parts.

D100 Build: A/C & Heater Hoses

I mounted the drier on the driver side inner fender, near the front. It’s tucked out of the way and offers an easy route for the -6 hose coming out of the condenser.
Doing the robot.
I don’t have any of the hoses tied together yet, but this will be the route they’ll take. Missing from this photo is the heater hose from the water pump.


II Much makes these handy anodized aluminum adapters to go from #10 heater hose to -10 EZ-Clip. I used a small section of rubber hose off the water pump, and then will use the Vintage Air reduced diameter hose to match the A/C hoses.
Check out the YouTube video on how to make the connections. It’s really, really easy!
The II Much bulkhead system is one of my favourite parts on this whole truck. I have one more hose to run, then I’ll be able to install the hose separators to really clean it up. It’s designed to fit the EZ Clip hoses, so you’ll have to decide whether you want to run normal heater hose from the water pump & intake up to the bulkhead, then use the adapters to switch to EZ Clip and go through the bulkhead, or run EZ Clip hose all the way from the evaporator to the engine. If you do the latter (my method), keep in mind that the heater control valve needs to be plumbed in the line coming from the intake, but the valve is designed to use normal heater hose. You’ll need to use an adapter before the control valve to convert from -10 to standard heater hose.
I thought there was going to be a fair bit of room under the dash! Get everything mounted that could possibly be an interference point. You can see the charge port on the -10 hose – check with the people who will be charging your system to see if they are ok with having one charge port inside the vehicle and one in the engine compartment.

Here’s a video showing the process of making a connection with the EZ-Clip system:


Dear Welder Series… What Steel Should I Use?

Dear Welder Series…
I have a 1957 Chevy Pickup that I need to get running before another baby comes in June 2018. One of the things I need to do is put a new chassis under it. Someone did a Camaro front clip on it before I bought it, and after doing some research and talking to people about it, and taking multiple measurements, I do not feel confident in how the clip was done. I actually have a brand new (covered in dust) Mustang II kit from a local company in Ontario, California sitting in the shed, problem is I need new rails to attach it too.

What type of steel would you recommend for making new rails out of? I have read a lot of resources that say “mild steel” but I am looking for more specifics like A-36 plate or A1011 Grade XX pickled and oiled, or perhaps some other awesome stuff I don’t even know about.

I know it is probably a dumb question because in essence, helping me does nothing or very little for you. Regardless, I appreciate it and hope you will consider getting back to me.

Thank you,

Dear David…
Hi, David.
The tubing for this is called Hollow Structural Section (HSS tubing). Specific info is at 2×5, 1/8” or 3/16″ wall will work well.

We suggest a 60” track width for the ’57 Chev pickup. You might want to confirm that the kit you have is going to give you that track width. If the lower control arms are stock length, the crossmember pivot holes should be 26-1/4” center-to-center.
I hope this info helps. Thanks for thinking of Welder Series.

Canadian Street Rodding Hall of Fame

Coming up in October of 2017 is the 23rd year of the Canadian Street Rodding Hall of Fame’s gala evening, and this year it’s on Saturday October 21st, 2017 BUT this year the location has definitely changed. The new location is the Cambridge Hotel and Conference Centre, 700 Hespeler Road, Cambridge, Ontario N3H 5L8 (click here for a map). We will meet and greet at 5:30 pm, with the meal and ceremonies beginning at 6:30 pm. Come and be a part of the induction of the 2017 inductee.

It will be a very relaxed evening this year in a new facility with proper visibility and sound and an open atmosphere. Last year we welcomed the Motor City Car Club as the first “club” to be inducted. This year’s inductee will be chosen from the nominations sent in by you. If you’ve not already sent in your nomination, please do so in the very near future. The deadline is May 1, 2017.

After the ceremonies there will be live entertainment and dancing for your enjoyment. A cash bar will be available and dress is business casual.

Custom Axle Brackets

We’ve always designed our brackets for 3″ axle tubes, but once in a while someone asks whether we can make them for other sizes. Here’s the process:

This can be done for any axle housing diameter, bushing width, or bar location relative to axle centerline.

We charged C$29/ea for the brackets, plus labour to weld them. Turnaround was a few days. Please get in touch if you have a special project that you think we can help with.

D100: Front brakes

There are a few directions we could have gone for brakes on the D100, but we decided to use our basic Mustang II caliper brackets and a replacement S10 caliper. They’re inexpensive, easy to find, and will serve our purpose well.

CPP has come out with calipers which have a 20% larger piston than the standard GM metric ones, and include pads for a very reasonable price. Here’s a link. They’re nicely powder coated black, and pretty sharp looking!

Rotors are standard Granada discs that you can buy from your local hot rod parts store. I got all these parts from Horton Hot Rod Parts in Milton, ON. I haven’t ran brake lines yet, so I’ll wait to run my flex lines. I’ll likely use a bulkhead fitting to go through the frame rail.

Here is the caliper bracket kit:

D100: Rack Extensions

Here’s a quick bit of info on how we matched the rack to our 62-1/2″ Mustang II crossmember.

Theoretically, you could widen a Mustang II crossmember as much as you wanted… the key is protecting the control arm pivot points and tie rod geometry. When you’re thinking of widening a Mustang II rack, there are two ways to do it properly… outside the bushings and inside the bushings.
‘Outside the bushings’ refers to pushing the tie rod ball and socket joint towards the wheel. This has to be done the same amount as the crossmember is wider than stock – typically 2″ per side on a 4″ wider than stock configuration. Longer tie rod ends can also be used on a 58″ wide crossmember.
‘Inside the bushings’ refers to lengthening the actual rack and rack housing. For a much wider crossmember, this might be a good option… there are even racks available that are wider than stock for this purpose. Your crossmember will have to be set up or modified for a wider rack. Welder Series crossmembers are designed to use rack extenders – the ‘outside the bushing’ method.

On my 1968 D100 truck build, I used a Welder Series 62-1/2″ track width crossmember, with rack extenders from Heidts. I used two (4″ total) on the passenger side, and one (2″ total) on the driver side. Our rack mounts favor the driver side, so the steering input shaft is closer to the frame rail and will be more likely to be aimed away from your headers.

Note: the rack bushings mount with the shoulder against the crossmember, and the serrations biting in to the rack mounts. Use a bolt size washer (included in our #24410 power rack mounting kit) on the front of the bushing, and let the bushing mushroom as you tighten the nut.

Syracuse 2017

The shop will be closed from Thursday till Monday while we’re at the Syracuse Nationals. We don’t have a booth again this year, but I’ll be around the Tucci Hot Rods booth if you’d like to talk with me.

If you’re on Instagram and Facebook and going to Syracuse, you’ll want to make sure you’re following us (just search for welderseries) because I’ll be posting throughout the weekend, and playing a little interactive game with prizes!

Thanks for your support. We’re looking forward to enjoying the weekend. Say hi if you see me!

Cruise Night Jun 21: Baden, ON

My oldest daughter Lily came to work with me today, and afterwards we wiped the car off and went to a cruise night! The location was really nice – we grabbed a burger and ate beside the mill pond, then checked out some cars. Here is some of what we saw:
