Flexing a Flex Plate?
Thanks for all the input. Responses to above:
Pilot hub dimensions are same with both TCs, and the new one does bottom out in the back of the crank.
The flex plate is a little bit concave - can't say if it came that way originally.
The Hughes documentation does mention use of "high quality washers" but in this instance I was wondering if adding more mass spinning around was optimal with external balance and all that.
