It looks like your photos didn't attach- - - -did you follow the tutorial at the bottom left of the page? This forum software is a bit picky about following instructions to the letter! Your best bet would be to find an original frame to match up with the body mounts and other critical dimensions. Try putting an ad in the "parts wanted" forum- - - -it's possible that someone nearby might have a frame. I have a bare frame, but it's for a long bed 51 GMC 1/2 ton- - - -probably not much help dimension-wise.
