that might be a direct bolt-up... I put a '98 cylinder on '91 cases.. I had to change the rear studs out for longer ones and modify the PV linkage a lil bit.. any cylinder from '92-'04 should work with your piston and crank.. I made the decision to use a newer cylinder after finding out the older powervalves were discontinued..
