The rear screw on a fatboy seat loosens then just spins. I'm guessing it stays in and pops off with seat? I can't get it to come off seperatly

 

Yep, it comes off with the seat/passenger pillon. Sometimes, most times, the two screws on the side tend to stay in due to the upward load. If you remove the pillon from the one up seat (two fasteners under) it leaves you with a nice big hole in the rear fender - see my recent post on this and the solutions to it - apparently there is a plug that HD sells - surprise!!!

Happy Riding!

 

Thanks for the help. much appreciated
