Hi Huib and Neil,
Thanks for the replies, the bearing I have here is a bit smaller, 62,36,14, I phoned another bearing supplier this morning, they said they had it, arranged for someone to collect it for me and guess what... It's not the same, it has an ID of 35 which I guess could work but the it does not have the protrusion that actually makes contact with the pressure plate!
I've attached 2 pics of them, the new one obviously in the packaging to be returned Monday first thing!
