Well I called a Yamaha/Cat dealer in the Mpls area. The guy at the parts counter had no clue. Then I racked my brain...hmm, Jeff Fischer from Motorsports Plus/Sledhead 24/7 tv show?....almost called him then I got a better idea.
M & M Powersports in Hancock, Michigan . Sure enough I got Chad on the line. He had a ZR9000 Cat on the floor with one installed. Compared it to a Sidewinder he had there. Said it might work but the Cat Grill and plastics are different. Though the sub frame is the same he said I might have to do some trimming on my plastics to make it fit. Now I am thinking I don’t want to do that. Good thing I was careful before I bought it.
