I had to shave my bolts a bit using the 80e and tci flexplate.

 

The motor been in the truck for around 8 months & just started making this noise.. I hope it's something simple. But thanks for the input.

 

Well looks like the flywheel is letting go. Sucker got cracks leaving every circle. Wonder what was the cause.
