G'day Riki, one of the most important dimensions in the uni joint excercise is the diameter of the bearing cap. The original is 1.172 " (1 11/64") and from all of my investigations there is no uni joint available these days with that size cap to suit the Packard senior set up. If that's correct then the only option is to use another uni joint (like the #1350), and I'm thinking it doesn't matter whether they are internal or external locks. Importantly though, the #1350 has a different size cap and the tailshaft has to be modified for it to fit. A correctly sized pinion yoke is required as well. My repairer reckons the tailshaft is easy to do as he simply cuts the existing yoke "ears" off, welds a new correctly sized yoke in its place, and then balances it all. In other words, no resizing of the old tailshaft yoke is necessary. Cheers, John
