i have the 2010 fatboy lo just bought the back rest for the bike detacble plates one thing what a pain to put it on i need my brother to help me put it on should be a one man job.. i called the dealership told me to bend the side plates i did still a bitch to put on.

 

My backrest was very hard to put on the first time. I had to basically use a pry bar to bend it enough on one side to get it on. After installing it a few times, its easier to put on now.
