David, 

Thanks for the pictures.  Have you done a full assembly fit check?  Have you done any ground runs?  Will the flywheel fit with the flat washers installed between Tracy's acapter and flywheel, or will those have to be left out?  

Mark  - on the verge of ordering a prolite flywheel.

Well, I'd say that pretty well seals the fate of using flex plates.  You guys all owe me a beer for finding the issue :-)

Here are some pictures of the machined flywheel that Kelly turned us on to (ACT prolite).  Weight is now under 9 lbs.  I think it is a good balance between weight and beefyness.  Someone with better access to a CNC could make the mods quick and easy, and the mods to that start/addapter plate are pretty easy.

Here is the front side.

I was moving stuff around in the hangar today&  picked up my salvage yard flex
plate. Found two 3/4" cracks: down from 9 o'clock&  up from 3 o'clock holes in
the pic. Plate has never flown AFAIK.
