the rear suspension is a piece of cake compared to the front. there are several styles to chose from, and that may be your most difficult decision to make. as to making the 4-bar, or 4 link yourself, you have the skills necessary, so it wouldn't be hard for you at all. the main concern is to keep the bars parallel, and to set the pinion angle up properly. spring rate would also be of concern, dictated on the weight distribution front/rear. don't skimp on the quality of the related hardware [ bolts, heims, bushings, etc.] and make sure everything is square / parallel to the chassis & front suspension when welded up and you will have no problem.
