Alternator bearing numbers on a 1991 DX 1.8 GTI Cabrio.

Asking here not on the electrical forum due to this being big block related.

Can someone tell me the bearing numbers for the alternator on a 1991 DX 1.8 GTI Cabrio? I want to buy them before taking it apart to reduce downtime on my daily ride.

Looks like a bosch model - what parts numbers are you looking for? Bearing 4 is showing two part numbers 021903221D or E and 5 is 054903221A.

I am looking for the actual bearing numbers not the VW part numbers, but thanks anyway. Further searches came up with these, 6203 RS or 6203 2RS and 6201 RS or 6201 2RS. I now have them available and hope they are the right size when I take it apart. I'll try to keep it in mind to update the post when I replace them.
