I have a 72 2 wheel drive stepside f 100 with a 302 and 3 on the tree and i would like to get a rolling chassis to drop my body on does anyone know if the body mounts are the same for other years and what is the range?

 

Anything from 67-72 should work not sure on the 250 chasis though. I also think that anything from 61-66 should work as well, but i would just find something from 67-72.

 

I know that at least 65 to 72 are the same. 73 to 79 are the same frame from the cab forward. From the back of the cab to the back of the truck 65 to 72 are a little narrower. You should be able to use the 73 to a 79 frame, you will just have to relocate the bolts to mount the bed down.
