Paul,
Taking the risk of telling you what
you may already know, I will give you what info I have.
The flexplates come from automatics and as such
are balanced in themselves, you may even see a balance tab on the
flexplate.
The manual flywheels are balanced units for the
model their on.
Therefore the flexplates need a counter weight
for the balance purposes i.e. front and rear counter weight for automatics/
flexplates.
Therefore any flexplate will fit any year model
PROVIDED the counterweight is that year model - I believe many counterweights
are interchangeable but I'm not sure which can change with which, best to get
advice from Rotary suppliers.
Like Ross if you wanted to used an aluminium
flywheel OR lightened flywheel (similar weight) you can use that as well
PROVIDED you get the right counterweight.
Hope that helps with your rebuild.
George (down under)
Thank you, Kelly. Paul Conner

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
