WTF is it?

It's the same cap diameter as a usual rover U joint, but the cross size is narrower. Anyone have a part # for Precision, Napa, etc??? I have no listing in the books here.

It's the solid shaft, 91 classic.

Thanks...

Napa 344 should work. If in doubt, remove it and take it with you to match it up.

If I am correct the larger is the 369 and the smaller is the 344
