Mine still has a pin in place Mike, but it's also still on OEM sizes. Before drilling out the new joint, can you get a roll pin to be a tight fit for the hole in the output shaft ? If not I guess the choice is either to drill both out again to match a roll pin, or, and I must admit this would be my initial choice, I'd just put match the UJ and put a bolt in.
Yes, terrible engineering I know, but if it had worked before......

made me smile. Instant memories of sitting on the floor watching Robert Plant with incredibly long hair & skin tight jeans screaming out "Immigrant Song" as the opening number in a gig they did for us students at Liverpool University in 69-70. Like you and the roll pin dilemma, I can't even remember the year.......
