That was some time ago, and I can't recall what it looked like where it mated to the flywheel.  Did the Ross also use an auto flex plate?  I remember the shaft was splined. That's about all I recall.  I am asking this, because I have purchased a set of street ported 4-port plates to which I will add a set of NA rotors and housings to build up a complete engine so I will lessen my "downtime" by hopefully swapping engines on a weekend. I would like to have this new engine ready to bolt on and run. I'm assuming  that  the stock, cast iron flywheel I have if from a standard transmission RX7. Are the automatic and standard flywheels different, or do you just add an automatic transmission flex plate to the cast iron flywheel I already have?  Just when I thought I had everything figured out, I start reading new posts about flex plates....
     Thanks in advance for any and all replies/suggestions.  Paul, what the heck is a flexplate, Conner
