Your best bet to buy all the parts you need for the 73+ BBP swap is DoctorDiff. He sells complete kits that are made up of all the 73+ OE style Mopar parts. Having a donor vehicle is nice, but after having done it that was as well you end up buying a lot of parts anyway. Often times most of your donor vehicle's parts will need to be reconditioned or replaced anyway, leaving you to buy new or reconditioned calipers, new bearings, brake hoses, etc. Unlike some of the other kits out there Cass sells the kits with Timken bearings, new lines, and has options for all the other stuff you may need as well. Keep in mine that 73+ BBP swap will also require either large ball joint upper control arms, or tapered ball joint spacers for the spindles.

A real loss for us here, he was an incredible resource for those of us with the '70 and '71 GT's.
