there is a few differant one's. kinda confussing cuz they got sev. diff. ones. I already have a swing are and axle from a 2005 Roadglide. to be quite honest. why cant I just go to the dealer and get the guts for the swing arm and the put some 3/4 O.D. to 5/8 I.D. spacers in for the pivot shaft. and call it good.
