I've never been able to find the part number for the thinner bearing. The one I have installed in my car came with a clutch kit from SPEC. I have two of the thicker bearings new in the box if you end up needing one. I thought I'd measure one for reference. Wishing I'd done that to the shorter one when I had it on the bench.
