If I recall the gen II box is a direct bolt on, but you don't use the top hole or somthing like that. It was months ago but I remember reeding that the gen II box makes a big difference when turning bigger tires. I hope I helped a little. It would be nice to have a compatability list of stuff that will work on gen I. good luck <img src="/forums/images/graemlins/patriot.gif" alt="" />
