I bought a spec stage 1 clutch and put it in and it chatters like crazy b/c of the flywheel. I bought a ford racing stock replacement flywheel for $119 and i was wonderin if its goin to fit on the cobra. They say the discontinued the cobra on. My ? is that the cobra stock one is lighter by 2.7 lbs and i could only find a stock one for 86-95. Will it work and if so wht are the pros and cons of it being a little heavier? Thanks everyone.
