Breaking Flex plates

Factory flexplates dont break under three times that load. There is a problem and "cheap parts store parts" are not it. While I agree PC diagnosing is not really the way to go, in this case, there's not too much else for options for things it could be. He could put on the SFI approved solid versions, and then he'll simply break or wear out something else. The down side is to properly indicate the bell, you will have to disassemble the trans down to the bare case to do it. You must use the same trans case you are running, and you can't indicate with the pump or guts in place...
