I have reservations about using needle bearings in this application. The design of the entire u-joint assembly is archaic. "Improving" it with needle bearings seems to me like putting lipstick on a pig, . .

In the early 40's Chev used needle bearing U' joints from the factory for a few years. They changed back for some reason.
It took them very little time to recognize that lipstick does nothing for a pig?
