Wondering if a sissy bar with detachable backrest that fit a '13 fat boy lo will fit on my '14 slim. I was told it was for a '09 night train or a '13 fat boy

 

my guess is since the rear fender for a slim is for a 150 tire an the fatboy has a 200 so the fenders are different widths...you might be able to space the mounts out....maybe they are the same but the mounting kit provides spacers.

 

Can you get some measurements from the current owner of the sissybar and then compare to your fender?
