Hey Bob-
I think you're talking about this part when you say pin, yeah?
I assumed since they were OEM rings they would be gapped correctly so I didn't check the spacing I just slid them in there so that the pins were between each end.
Am I correct that the best way to check the gap would be by taking the rings off the piston, sliding them into the cylinder bore, and using a feel gauge to measure between the two ends? (edited)
