I am going to purchase a clutch kit from sho nut with the upgraded bearings but I need to know if the flywheel on my 89 SHO is 9.25" or 9.75." The previous owner replaced the clutch at 29,000 miles and here is the part number on the receipt: 1 F0DZ*7A537*A (kit cl) and here is another part I don't know if its the flywheel or what: 1 F2DZ*7548*B (hub & brg). Can someone tell me if that is the flywheel and clutch or when I purchase the sho nut clutch that I have to also purchase a 9.75" flywheel? ALSO, if I do have to buy both, what new bolts and misc. parts will I now need? THANKS FELLAS FOR ALL YOUR HELP!

F0xxxxx sounds like a 89-90 clutch. The current 9.75" kit is a F1xxxx part number.
F2xxx is the new style TOB I believe (nylon hub, steel sleeve).
Easiest way is to take the starter off, and inspect the flywheel/side of PP. If the PP continues to "run" beyond the flywheel and seem the same size, then it's a 9.75". If the edge of it "disappears" behind the flywheel, it's the smaller 9.25"
