1968 GT500KR Flywheel. 428CJ.

[Craner]

Still looking.
I did purchase an NOS flywheel.  Upon receiving the flywheel, I noticed that every pressure plate mounting bolt hole/thread had a "plugged" hole and these broke into the section where the pressure plate bolts fasten.
I've discussed this with my engine builder and he is telling me to locate another flywheel. He is concerned about using it

I'll really prefer using the cast iron design.
Does anyone have a used proper stamped part number design that I can get resurfaced and install a new ring gear?
Any leads appreciated..
Thank you
