Hey Naj, George, Hugh, Ben,
Thanks for your replies.
I have found the other “standard” number.
When the local bearing shop guy asked me what year the car was, he ducked out the back and came back with the SKF and FAG catalogues of the same year.
He asked for the MB part number and then proceeded to find the correct bearing number.
The SKF catalogue had no reference at all to the MB 000 981 05 06 number.
However the FAG catalogue showed the RH Side bearing standard number to be
20208 with a follow up number 565 889 F51 that he said would be a drawing of the bearing.
He also found the standard number for the LH Side Bearing 6208 with a follow up number of C3, 361612
Again, thanks
