ummm, the housing flange bolt patterns are different on the 15 and 20.

btw one rear-disk place, tsm, says the amc20 flange is the same as
ford 8" and 9" small retainer, and some dana44s.

starting in the late '70s, 10" drums became available on some amc15s -
spirit amx, concord wagon, eagle for example.
