Default *NEED HELP* flexplate to th400 needed vendors welcome..

I am in the middle of a th400 swap and NEED FLEXPLATE advice.
The flexplate I originally got is an curved hughes sfi for a gen 3 block. I recently changed to a gen 4 block.
Will I need a new flexplate? Or just an adapter?
Recommendations?

Tranny is a rossler TH400 t2.5
Converter is a PTC 8inch specd for stock style flexplate.

Any info or suggestion helps.....

Nope, Just put it on and run with it. Beware though, you will probably have to grind a couple of the flywheel to converter holes. May want to check while they are out of the car. PTC uses the large bolts.
