My rear ended up costing a couple hundred more than building a 8.75 from scratch. I figured the wow factor was worth it. Since my convert had the puny 7.5 rear I didn't have anything to start with. Dr. Diff drop shipped the housing to me from Strange engineering so I could mock up the panhard bar, sway bar, and three link mounts. I shipped the bare Strange housing after I mocked it up to Cass (Dr Diff), he built the axles, finished the welding, bent the brake lines, assembled the brakes, installed the gears, and powdercoated the whole shebang. Awesome work.
