Before spending big bucks with Fusick, here's another thought. The 62 D88 uses the same 11" x 2" rear brakes that have been used by GM forever on full size cars and half ton trucks. All of these have the 5 x 5" bolt circle. If function matters more than absolute correctness, I'd snag the rear drums off an 80-90 B-body wagon in a wrecking yard and try it for size. If it works, great, and if not you're only out $10-$15. Note that only the wagons and police/taxi four doors use the 11" brakes and 5 x 5" circle.
