1954 Chev car hubs and backing plates will get you a 5 lug pattern and then you are open to choose a matching five lug rear end. If you go this route, you can use your existing master cylinder, lines, etc. With the disc conversion, it gets a little more complicated. See the "Parts For Sale" for a set of 1954 Chevrolet hubs and backing plates that are listed there.
