   * By the time the 1976 parts catalog came out, all three early transmission sprocket versions were available for replacement of the original no matter which bike you had and from 1954 to then current. It stayed that way until Late 1979 in the parts catalogs. However, 1973 and up Sportsters all came factory with a 21T sprocket, according to the FSM. There is also an overlap in 1973 in that the FSM(s) states a 21T and a 20T for 1973 ((The Doctor71 of the XLFORUM)). Maybe a mid year change?   * By the time the 1976 parts catalog came out, all three early transmission sprocket versions were available for replacement of the original no matter which bike you had and from 1954 to then current.
