Many Thanks to both of you Andy & Graham for your help.
Interesting that your car has the 207, mine like Wescott has the 210.
The 207 seems more "standard" and used on more recent cars.
The 210 was a real pain to find not considering that the first supplier I found would not accept to ship to France !
I just finally got them from ABC Autosport Bearings & components Unit 3 Shepperton Business Park, Govett Avenue, Shepperton, Middlesex TW17 8BA
Price is £75.63
Interestingly, they are not on their catalog of parts buts they seemed to have some "spare" left.
These bearings are just being put back on the car today and I will be ... back on the road
Many Thanks again
Laurent
