For those who still have this rear drum dilemma, I ended up finding the NAPA equivalent of the Centric 122.66028 (Wagoneer drums). I measured them next to my stock rear drums and I think they're going to work, with the additional machining as mentioned before. The NAPA part number is 440-1361 and I paid $25.83 a piece. Now I gotta find a shop to do the machining.
