Was at dealer in my area. Parts dude said he found a solo spring seat for 04-up models. Dunno if its an HD part, how much, etc. They'll be in next weekend. Plan on riding out there and checking them out. Hopefully they'll let me slap one on for looks and take a few pics. If so, I'll get the info and pics and post here.

 

If you end up with it, be sure to post a picture or 2.

 

Cool, looking for one of those myself.
