ok i bought a flywheel a couple months ago for fox 351w project im doing.....the flywheel is on the engine right now and i was going to put the clutch assembly on today...but the pressure plate bolt wont line up with the flywheel holes....i measured the pressure plate diameter and the flywheel diameter, the flywheel is 1/4 smaller...(the clutch is a 10.5")..then i counted the teeth on the flywheel theres 160...(didnt know they made 160)....i bought the flywheel on ebay, the guy said it was a 157 tooth 28 oz, which was what i needed, but now it wont fit??...would i need a 164 tooth since its topo small?? any ideas on whats wrong? thanks
