I think a Vmax 600 secondary might, but i'm not positive. check out www.vmax4.com You'll find a wealth of info on that site and many V4 experts that can help you.
What do you mean by fit? The spline depth is different than 97 and up as well as the 800 moveable sheave is undercut in 2 places to make it close further, what is it you need??
