I have a bad roller on my 2007 four weight clutch. I know I have to get a new three weight with the four being obsolete, but if I buy used can I get anything (i.e. rollers, spiders) for it? Arctic Cat has no part numbers for the spiders anymore and I've heard that's there's a legal reason why. Does anyone know or can point me in the right direction. Anything would be more than what I know right now. Thanks.
