Questions about frame and drive line

[52ratrod]

Hey guys new to this forum and can't tell you enough of the great information that is being passed on.

I bought a 52 SB 1/2 ton and want to start getting parts lined up and tear down under way. A previous owner had completed a semi resto but every thing needs to be redone.

What I'm trying to figure out is the frame and front end they used. It looks like they swapped the frame but didn't use s10 frame. The front end looks like a 60-80 IFS that has been bolted in.

The frame has cab mounts welded in but the frame looks narrower because new cab mount bolts were installed inward about 2inchs on each one.

The rear end is a 12 bolt that has been mounted also.

I will try and get some pics up so you can see what I'm talking about, thanks in advance for any information.
