87 frame question

[mud bug]

is there any difference between a 2wd and a 4wd frame? im not talking about holes where the front end was bolted but like width or boxed/not boxed or any different bends?

The 4x4 frame is straight and the 2wd is indented for the front independent.

is it a major difference? i tryed to look up pics online but couldnt find any good ones.

no major difference. both frame rails carry the same part numbers in the GM catalogs. if you're looking to convert one way or another, its 100% bolt on, and has been done dozens of times.
