    i can get a "project" 69 pickup for cheep to nothing but it is 2wd. are the front frame horns the same dimensions as the 4wd ones? i have some front spring hangers and could get the rear shackle hanger out of LMC. then just drill the holes in the frame where needed.

    anyone got anything on this for the 67-72 years?

    someone posted awhile back that frames were same you can swap crossmembers in and holes are already there. if that is the case they must be alot different than 2nd gen cause isn't the frame totally different 2wd to 4wd? /forums/images/graemlins/dunno.gif

    Frame should be similar -- I donno about first gens, they may be weird -- but the cabs are usually different, so the general consensus is that you'll need a body lift, a new center hump, or soem serious BFH to make the tranny/transfercase fit.

    OTOH, if you're swapping cabs, this is a nonissue.
