Cummins Transmission crossmember
 

Anyone have pictures of their transmission crossmember?

I’ll soon be fitting mine and looking for ideas...I’ll be running a 47RH transmission

Attached photos of my progress - 1972 suburban 4x4 frame, Cummins 12v with Rob Bonney box kit - I’m not the welder.

On my 72 I used 2x4 1/4" wall and made a completely new cross member. Using a stock cross member will be tough because your boxing plates won't allow the stock one to set inside the frame. Unless you plan to bolt it under the frame?

much better options out there or fab one to match your rails

Dieselwrencher -

What did you use then for transmission mount? I’m referring to the rubber mount that buffers vibrations etc

I used square tubing and the stock mount just made a adapter.

I don't like being negative, but i have to ask if you have trial fit the motor in the mounts with the cab and core support in place. I also bought the rob bonney mounts and frame kit and just started assembling it all. If i remember correctly the instructions said to start mount placement 18" ahead of shackle mount. I found that to be about 5" too far forward. Using the 3 holes on top of the frame as reference, the front of the motor mount plates line up with the rear hole. Looking at your pictures, I'm afraid you may be 4-5" too far forward. I hope I'm wrong for your sake, but I had to ask because your pictures don't look like mine.

In the picture my engine crossmember isn’t welded in place - it’s to be determined where it will go based on test fitting the engine & transmission.

Engine & transmission should be back from the shop & will take it and frame with body bolted to the frame back to fab shop for final fitment.

I’ll post results soon

I used a stock 84 cucv cross member and dodge mount when I had a 47rh. then when I went to a nv4500 I used my stock 88 cross member and mount.
