Does anybody know what ball race release bearing can be used for a 1098 clutch? Mine has a worn housing and has done a few miles and I want to replace it. Ideally I'd like one to swap out rather than trying to swap over the housing due to time constraints. Also it seems to be pressed in around an aluminium sleeve and that will end in tears if I try removing it.

I don't want to pay £80 +vat (

) for a new one. Similar MGB ones are less than half that and the original one cost less than £20.
