Sorting out contents of shed came across 2 new CV joints(to suit Cooper S) made by Thomas Bell had them since late 70's anyone have any experience with this manufacturer?The protective boots are U/S.Many people both here and overseas complain about the very short life of boots and other " rubber components",is there a source of high quality rubber bits(Japan)? Also I believe there was/is a series of problems with aftermarket Pot joints is there a supplier of quality items? Thank you.
