I've started looking for a new flexplate that will fit my 8 bolt crank and the 4 bolt to 8 bolt torque converter adapter. Do you happen to know if the adapter has a 11.5 inch pattern for the 4 bolts? The Performance Automatic P/N PAX28111 ($145) supports multiple torque converters but I'm a little concerned about the number of holes.

JEGS has an 8 bolt crank flexplate with 11.5 inch 4 bolt pattern (P/N 601094) for $60. It is only 3.5 mm thick compared to PA's 4 mm thick flexplate. I don't know the OEM flexplate thickness. I'd rather not have to shim the starter motor mounting to get the proper alignment with the ring gear.
