help body mount differences - The 1947 - Present Chevrolet & GMC Truck Message Board Network

so I need new rubber or urethane mounts for my cab and radiator support, the problem is when I look them up it lists 67-68 and 69-72 is there any differences in the mounts? is it just the rad support mounts that are different because 67-68 are different rad supports from 69-72 or are the cab mouts different as well?

I have a 67 chassis but I have a 71-72 front clip on it and a 68 cab and the gaps on the fenders wont line up with the doors so I need to get new mounts and want to make sure I get the right ones, if anyone can point me in the right direction that would be awesome thanks

Not to hi-jack but I have the same problem. The body line on the bed is 1/2 inch higher than the cab. I am using the poly mounts and have switched from a steel bed floor to a wood bed floor, not sure what to do either.

From what I understand the difference is in the core support mounts. Keep in mind you need to reuse the thick washers from the old mounts. Bed goes on first, then cab, then front clip. 70CHEVYBB, I would suspect the poly mounts are not thick enough, your going to have to use shims or go to rubber.

We used a different sequence when we did the build on my '67 on a '69 frame.

We used poly mounts and did not have a lot of problems.

We put the cab on first, then put the front clip together on the frame and then the bed. We did have to use a few shims here and there to get things to lineup.

We did use the thick washers because the kit I bought did not have them.
