Thanks, Ed.  I have to admit that I am still not certain that I understand everything I need to know about the flex plates, etc.   
 
Hi Paul,
 
Maybe I'm missing something, but why do you need to know anything about flex plates for your engine swap?  Aren't you going to install the Ross drive on the new engine?  If so, wouldn't you also move the Ross drive plate (with the springs) and or flex plate at the same time?  I just don't see why you need anything new.

Hey, Rusty....yes, I would install the Ross drive on the new engine, along with the Ross drive plate that has the springs.  I just thought if I had the proper flex plate, it would be an easier engine swap if I just have to remove and reinstall that triangular looking plate with the springs.  I understand that is the drive plate.  What the heck is the flex plate....are we talking about the cast iron flywheel?  That is harder to exchange, because of that large 2 1/8" nut .  If I just have to remove and reinstall the triangular Ross drive plate that has the springs, and it will bolt onto the flywheel of the standard transmission engine, then I am all set.  Paul Conner
 

 Paul,
 
1.  There should be no reason why the flexplate (to which the triangular thing with springs is bolted) you are using now should not work. 
 
2.  You do not use the flywheel which is a very heavy (like 25+ lbs), the flex plate is similar in size but not thickeness.  Its stamped out sheet steel and has the ring teeth welded to its outer perimeter. If you have to grunt to pick it up then its a flywheel {:>)
 
3.  As best I recall you can remove the triangular piece with the drive spline without removing the flex plate (its held to the flex plate with 3 bolts) - however, that does require of course that your new engine have the flex plate mounted.  You can not mount the triangular piece on the flex plate before mounting the flex plate to the engine because then you have no access to the flywheel nut that holds the flex plate.
