The 87 SS came with a complete Shimano 600 6208 series group- the whole dealio. Have seen some different rims on different bikes, but everything else in the drivetrain (hubs, freewheel, derailleurs, crankset, brake levers and calipers) was 6208. Lots of that out there, mostly individual pieces. Watch out for shifters that have all or most of the indexing tabs broken off, a very common problem that renders them useless.
