What are you going to do up front? If you want to match the rear you'll have to upgrade the front as well. I'm using a Chevy II rear & the IFS from a 79 1/2 ton. I had the rotors redrilled to match the rearend. Most of the Camero/Firebird units thru '81 work fine. Early Nova's work also. There are many choices out there but it depends on how you plan on using your truck.
