hi, I think it should fit fine. I'm 99% sure the major metal engine bits stayed the same from gen1->2 but I don't have a gen2 to compare to so can't be 100%, and that doesn't rule out some minor change.
Remember to get a fresh gasket for the clutch casing too as removing it is usually messy. I did a video on the clutch change process on youtube. soetimes it's helpful to walk thru the process beforehand.
