After disassembling the used u-joint, I started to install the new rebuild kit.
The new ring "Bearings" were a very tight fit into the u-joint body - I measured a 0.004 - 006 interference fit. I installed one ring in the body to check and the interference fit caused the u-joint pin to bind.

I ended up carefully grinding out the u-joint body holes so there was only about a 0.002 interference fit and the u-joint worked fine. I checked each pin fit by temporarily installing the ring into the enlarged hole before reassembly.

One more reason to measure all repro parts for fit before you install them!
