Not sure about the years and models, but in my experience ( couple of 500cc tanks mounted to bonne frames) you will need to roach out the forward mounts because the holes in the 500 tank for mounting are spaced closer together than the bonne tanks. Also, you might have to elongate the hole in the rear of the tank to go on the spud on the rear of the frame. Couple hours of fiddling and fukking around and you will probably be good.
