OK Paul, I have been out of town so may be late with this info = !!=20 Ross
used the flexplates from the 12A to 1973 = and  (some=20 1974) top mounted
starter rotary engines until they became hard to find....Then = they=20 started
making them from aluminum and adding a ring gear for the = starter !!=20 These
flexplates are smaller in diameter than the later = ones......FWIW
