Kelly, how is the Ross flexplate attached to the counterbalance?  Is there room enough between the damper plate and flex plate?
OK Paul, I have been out of town so may be late with this info !! Ross
used the flexplates from the 12A to 1973 and  (some 1974) top mounted
starter rotary engines until they became hard to find....Then they started
making them from aluminum and adding a ring gear for the starter !! These
flexplates are smaller in diameter than the later ones......FWIW
