I'm putting the cab back on the frame of my 77 F150, but I had to do some repair work on the cab mounting brackets on the frame. The brackets were rotted somewhat where the bushing sat so I cut the bad spot out and plated the mounts. My question is, can anyone give me dimensions of where the center of the hole should be for the bushing to fit in? I can mock up the truck to make sure everything lines up before I mark and cut the holes, but it would be nice to be able to cut them now. Thanks guys.

 

Why not measure the center to center distance of the holes in the cab?
