Ok, I have a few questions. I keep hearing reference to "deluxe" backrest, verses non-deluxe. I have a 1300c. Can anyone tell me the diff, as I may end up buying my backrest piece by piece and want to make sure everything matches. Also, I heard 1 retailer say that deluxe backrest doesn't fit ultimate seat. Is this true or is he full of it? I know ultimate called me before sending my new seat to make sure I didn't have cobra, because they said that that would influence the type of pass pillion they sent. They sent they one that won't work with cobra.
