We're redoing the forks on a friend's 1977 FLH. Everywhere I go to look into parts (for other parts, as well as the fork rebuild kit) I read about the "early" versus "late" 1977 models. Can anyone tell me how to determine if the bike we're working on is an "early" or "late"? I would assume by VIN, and this bike's VIN number is relatively low (well below 15000) that this would be considered an "early" 1977. Good assumption, or not? Thanks for any and all help!
