I tired to send a PM but your box is full.
So are you saying the shaft has been fitted with a groove for the o-ring or the PI converter has the grove in it for the o-ring and the shaft is still untouched?
Has then converter and/or shaft been used in a car yet or still are they still new?
What was the converter setup for, lockup, non-lockup, stall @ tq?
Is the chain setup new or used?
