Earlier tonight I started to search on a new flywheel for the Monte as the one I had in the car has a wear ring with just enough of a step down from the rest of the face of the flywheel. The best budget deal is the Luk for under $60 (under $70 shipped.) But local I could cut it for under $50. I have an extra but it is a marine p/n & waves more than a flag in the wind (never surfaced.) I would like to keep an original flywheel but new "should be" flat & ready to go for the engine/transmission install in the frame. There is no heat damage just the wear ring & the thickness seems to be very close to the average measurement on the marine flywheel using both of their outer diameter. I gotta spend money anyways so I wonder if the Luk would be better than cutting an original GM.
