Aside from cost, are there any fitment issues? I am looking to install an aftermarket performance single disc clutch, and the same stage/material clutch for 97+ is $400 less than the single disc for 1991-1996 models; both are single disc, but the part number is different between the two different year ranges.
What's interesting is the part number for the 1991-1996 clutch, with lightweight flywheel option, is the same as the part number for the 1997+, with lightweight flywheel option, but the clutch by itself, has a different part number.
