with the IMS 3.2 gal desert tank. The braces actually hit the tank and don't allow the mounting holes to line up. I'm gonna try a couple of options to make it work. First, I'm gonna try taking off the tank. Then try mounting the braces and the tank back on. I really don't think it will work, but I want to try it before I try plan B. Plan B is to knotch out the braces to make them fit with the 3.2 tank. I already talked to W.C. and they weren't aware of the problem (in their defense, they do tell customers that they will most likely NOT fit with any oversized tank.....just to be safe, even though it might work with some tanks). My buddy has an '04 450R with the IMS 3.2 tank and the braces cleared the tank and mounted perfectly. The rep. at W.C. said that he thought the '05 worked as well with the 3.2 tank. He sounded a little shocked about it not fitting with the '06. Maybe IMS redesigned their tank for the '06? Just wanted to let some people know if they have this tank and are looking for braces, this combo will not work without modifications!
