Flex Plate not flush with TC

I am not sure what the tolerance is for Chrys, but you would NOT bolt up a GM FP with 1/4" clearance. In operation, the FP....flexes....& moves towards the block. So that 1/4" gap gets larger...& the c'ter might disengage the pump drive.
I would see if you can get another FP to compare to see if this one is bent.
