I have a 86 4wd: everything is good except for the rear frame
Found a deal on a parted out 87 2wd with a good frame (2 hours away).

Is the back section of a 87 2wd Frame the same as the 86 4wd Frame?

In other words, can the back of a 87 2wd frame be matched/welded properly to the 86 4wd front? Would any other rear mounting modifications be needed?

Thanks in advance for any information on these frames!

 

the 4wd frames are fully boxed, i think the 2wd frames are C Channel.

 

My only reference to the 2wd frame is a photo in a Haynes manual, page 10A-2. It shows a 88 2WD and the frame from below center, it appears boxed (at least on the insides). All other mounting points appear similar to that of the 4wd.

 

hmm, i may be wrong, ill let someone who knows more about this chime in.
