Looks like the auto tx flex plate ring gear is larger as well.
Its this getting more and more complicated as we go along.
I suggest putting in the stock auto tx flex plate and ring
gear. This is a real can of worms. An early starter may not
work with this ring gear because of the tooth form.

Here are your options as I see them right at the moment.
You can switch the flex plate and the starter for the 2nd gen
RX7 13B flex plate and starter or you can have a longer psru input shaft
made for Tracy's psru and use the stock Cosmo bell housing like
Bulent is doing. This will work for a pusher. It won't fit most
tractor cowls I suspect. You would be on your own for motor mounts.
