I am switching from my Ross Gear box to Tracy Crook's RD-1B redrive.  I
discovered that (at least on my Ross drive)  the automatic transmission flex
plate that Ross used is 1" smaller in diameter than the standard 13B flex
plate.  The plate in my Ross drive measured 11.7" tooth tip to tooth tip,
where as the 13B plate measures 12.7".  This means that 1.  the RD-1B damper
assembly will not fit the smaller flex plate and 2.  The starter hole would
not position the starter to engage the flywheel gear ring (a moot point as
the non compatibility of the plate with the RD-1B damper assembly would
preclude you using the smaller flex plate)

Came as a surprise to me, could this be a 12A flex plate?
