So i just got done taking the 2 speed idler gear and drive gear and put them on my 3 speed. It was SOOOOOO EASY. All you need is a dremel! The link below is to the thread where i found out how to do it. Its a bit confusing but after you look at a 2 speed and 3 speed apart you see what its talking about.
