While rummaging around for all the New Parts that are going along with a gifted 3,4L V-6 Engine… I dug down inside of the box holding a pristine Flex-Plate and THIS Warning message was printed on an 8”X11” Color Flyer inside:
Warning:
The Warranty is VOID if the Flex-Plate Assembly is Broken around the Crankshaft and/or Torque Converter Bolt Pattern…. (The Warning is repeated…)
The Warranty is VOID if the Flex-Plate Assembly is Broken around the Crankshaft and/or Torque Converter Bolt Pattern….
Reduce Failure:
Check Engine and Transmission Mounts and be sure they are supporting Drive Train properly.
Replace Broken-Worn-Out Motor Mounts… Match New Part to Part being replaced… Always use a Torque Wrench … Never Over-Tighten or use an Air Wrench… Use New Flex-Plate Bolts.
So… in support of the great write-up done by @Capote last September 2016 regarding him conquering the odd destruction of the center of the Flex-Plate in The BatBlazer:

I thought this information might be worth adding or remembering if the Motor Mounts or Transmission Mounts have NOT been replaced and this Flex-Plate Cracking Problem gets discovered requiring that they get R&R'd.. Apparently, the company making the Flex-Plates has determined that the Failed Motor Mounts are involved as a direct cause for this kind of Flex-Plate Cracking Failure. Here is a link to the scanned image of their Warning Flyer of the text echoed above:
