I think the 2012 was a 10.5L tank and for 2013 they went back to a 9.5L to improve fitment. I managed to cross thread the first 2 threads of my mount due to poor fitment issues. I then filed/sanded the hole in the tank to align at a better position and angle. Finally went to a longer bolt rather than only having 3 threads attach to the frame.
Got any pics of the damage Nato?
