I know this is about a decade late, as you already figured out a way to mount yours, but for anyone else who is really lazy - I found a 1" ball with the correct stud from HuddExpo. Stupid expensive at $20, but plug and play.Ok you guys, I bought the ftm-100dr and am getting it installed this weekend. I’m going to mount the head unit on a ram mount next to the shifters. The remote head unit has a threaded mount on it and if I can just find a 1” ball with the right size stud...I’m in business. Anyone know the right size stud for the head unit?
