Paul here’s a thread in the same vein as yours. There are pictures of two types of clutch release bearings on a link he posts. [xk] Re: 4.2L clutch release bearing
Here’s a further link with yet another photo of a release bearing. You’ll note it’s unusual thickness. I believe this was introduced late by Jaguar for use with hydrostatic slave cylinders. These were causing premature wear so Jaguar produced this extra thick bearing, and I’m sorry I don’t know the part number.
