I must be tired, I didn't either........I read somewhere that there is a few minute changes in 07. some of the accessories won't fit a 07 but I can't remember what they were - gettin old I guess.......
I know that, after shopping for parts for my 07 retro, the spacing between the rear fender bolts is different. Different Sissy-Bar mounting brackets needed for the 07, thus making it nearly impossible to find a used one.
That's the only difference that I've learned of so far... and that's on a retro, don't know how the C models compare.
I just realized that my ramblings here are, probably, of no help to you. Sorry if I have wasted your time.
So, are you saying I can't use deluxe mounting brackets from an '06 for my '07? I just want to double check. I'm about to order a ton of stuff for my 1300 and I don't want to have to send back stuff. Thanks!
