Hey guys, just wondering if anyone knew if there was a difference in 2wd frames and 4wd frames from the cab back, My frame has some rot in it and has been patched by the previous owner in some spots. I have an 85 2wd truck with a blown motor and body damage but the frame is pretty clean, Just wondering if I could clean up the 2wd and backhalve my frame right after the cab on my 4wd?

I dont think so ...

2wd's had a 2X3" box on the rear 1/2 ... 4X4's were 2X4" boxes ...
