I kept my custom C&C seat when I traded my '08 Street Glide for my '14 Street Glide. The only miles on it are from the service guys. I swapped them out to ride it home. Its a great seat I just need one that puts me back 2 inches. Looks like the SG seat was redesigned a bit for the Rushmore bikes, it has more padding than my '08 did.
