Part number 43041-1764-GN LH and 43041-1436-GN RH used on 1994-1999 according to the Ron Ayers parts fiche... No other type Kwacks were listed as using those calipers. From 2000 to 2004 a different part number was used. With that being said, I'm not familiar enough with the calipers on those bikes to know if other years can interchange or what the changes are between part numbers. Interestingly it appears the rebuild kits are the same from 1994 thru 2006. I've rebuilt calipers and it's not that difficult although a trifle messy.
