I kept my hd adj. back rest off of my 11 tg when I traded for a 14 tg. I know hd said it wouldn't fit BUT I had to check it out, bracket bolted right up no modifications. I did route the cable for the adjustment lever a little different, works fine. I do take the back rest off and on a lot and I think it might be easier to get the back rest in the bracket on the 14 than it was on the 11. both the 11 and the 14 had stock seats.
