The syncros seem to be 123 262 01 34 and 124 262 00 34. There are two of each, 1st and 2nd are the same and 3rd and 4th are the same. The gear seems to be 123 260 06 25. The bearings vary by transmission number (I could get this from the chassis number also).
I don't have any of those late model syncros. The part numbers I have listed are for the brass "blocker" rings. The syncros are actually an assembly of different parts but the "blocker" rings are what are usually refered to as syncros.
