I've got an opportunity to buy a '56 Frame that's had a 70's nova subframe grafted to it and a GM rearend above the springs for very little money. I have a 57 F100. How different are the body mounting points between the two? Thanks in advance, John

 

I think this was asked once before and I thought there wouldn't be much difference but was corrected if I'm not mistaken. I still think if you have your 57 frame you could likely move all the mounting hardware with some careful measuring but don't hold me accountable.lol

 

This one has the front stub for the radiator support welded onto it. I know the support for the '57 is different. I don't know how different the cab mounts are. I assume the bed mounts are pretty similar, if I'm not mistaken, they used the same flare side bed up to the 70's.

 

If someone has pictures and measurements of a '56 I could take them of my '57. Let me know by email, as I am not on as much as I'd like.
