Just got the HD accessories catalog today and saw that they are now making a pretty cool looking brown leather solo spring seat. I have an '07 Nightster and figure it would ft my bike since they have a Nightster in the example picture, but it says all 2010 and '04-'06 XL models. Does anybody know if it will fit the '07 Nightster or did they change something in the new Nightster to make it compatible with the setup?
