Hey folks ; I'm wondering. What are the differences in the fork lowers (the alum. part) across the year models? Mainly how can they be identified. I've heard that there is a length difference as well as a difference with the internels. The main reason I'm asking is because I'm wanting to replace my lower right fork tube because a PO ground all the mounting points making it impossable to mount my fender in a normal manner. How can we identify these lowers?? I found a fellow member here that had a fork lower that he says is off a 1976, it measures 12.5" and another one (on Hondachopper) who's lower measures 12 5/8" I measured mine which is on my 1976F1 and it measures 13 7/8". Both measurements from the top of the lower to the split where the cap goes on (cap studs Not included in measurements). This is why I'm confused. Thanks, ...cougar... P.S. I can't post any pics because of Internet problems (Dial-Up).
