Green Bearings on Moser axles

After talking to Dr. Diff the other day, he explained that the early open pigs had a more squarish looking center spacer (which I had in my 741 case) and the sure grips have the button type spacer(s?). Anyway, I politely asked Cass to send me a new sure grip (after giving my cc number ;)) since I had to pull my carrier to get the spacer out, and will be running this new repro clutch sure grip with the button spacer(s) removed... in order for the Moser axles to fully extend into the diff....
