So....trying to convert a '68 'burb from 2wd to 4wd using pert near everything from my wrecked '70 Jimmy. It is definately not as simple as 'unbolting from the Jimmy, bolting on the suburban'. The first problem encountered is WRT the suspension. The burb has a coil spring setup. Pulling off this crap is not that difficult, but the first thing I noticed is that there are no leaf spring mounting shackles. Will this be something I will have to grind off the Jimmy and weld onto the frame of the suburban, or is there someplace that sells the leaf spring shackles so that I can just mount them to the burb frame? Thanks.
