Dear Welder Series… Transmission mount for ’56 F100?

Dear Welder Series…
I’m building a 1956 F100. Supercharged 5.4 with 4r100 trans. I have purchased your engine mounts, but I’m looking for a tranny mount that will work with the 4r100


Dear Andy…
Andy, have a look at our 2115 trans mount and crossmember:

and the 205043 Ford adapter plate:

which use the insulator/rubber mount:

205041 has recently been modified (now #205043) so it will work with transmissions that have rubber mount hole centers from 5-5/16″ to 5-9/16″. All of this has to be filtered by you knowing that I am not at all familiar with this transmission, except by looking online.

Thanks for looking to Welder Series on this problem.

Dear Welder Series… custom transmission mount

Dear Welder Series…
Paul and Dorothy,
Ordered some parts from you all a couple of weeks ago to make a trans mount for a 1990 corvette trans that I am putting in my 56 Chevy pickup. Paul even call the day after I ordered to make sure I ordered the correct parts. Thanks, I appreciate that. Paul said send some pics when I got it made and on the truck so here it goes.

Dale cherry picked some brackets from other transmission mount kits and made his own. He used our 350 adapter plate, a shock mount plate, and a little tab that normally welds into the adapter plate, but he only used one side of it. You’ll understand when you see the pictures.

This is one of the reasons Welder Series is here. Thanks for being creative, Dale.

Dear Welder Series… GM SM420 Transmission Mount?

Dear Welder Series…
I ordered universal motor mounts an the tranny kit. The motor mounts will work fine. The tranny kit baffles me at this point. It is a beautiful design, and I would like to use it as it will give me plenty of clearance for dual exhaust.
The tranny is a SM420 that GM used from 1947 to 1967. It is a 4 speed manual with the lowest 1st gear ever. Pretty popular with Jeep people these days. The tranny mounts at the bell housing.

I noticed on the web that many 4 wheelers have transfer cases attached the would mount from the back. This is going into a 1962 Dodge d100 truck. 2 wheel drive (no transfer case).

Let me know if you have any suggestions.

Spoke with Paul yesterday


Dear Rick…
Rick, it looks like a crossmember will have to be fabricated with tabs or bosses to line up with the holes in the transmission.  Urethane bushings could be used at each end of the crossmember to provide some insulation.  Brackets welded to the frame would put the urethane bushing in double shear.

I hope this helps feed your imagination.
