Like Dusty said, make sure you got the right setup. The R rack and backrest is wider than the C. If you've got all Hondaline stuff then they should bolt up quite nicely. But keep in mind that the rear fender (at least on a C) is tapered so to make the bags parallel there has to be spacers . The back of the bag will be further away from the fender than the front, but they'll be parallel.
