Alright......here is the deal..... i have an 86 ford mustang lx 2.3 n/a with 4 speed MT. well the clutch disc........went on vacation....the half facing the flywheel is fine but the half facing pressure plate is GONE.....its resting in peices on bottom of tranny. well the pressureplate and flywheels are in A-Ok condition no scratches or gouges from rivets... my question is.......how big of a clutch disc and pressure plate can i put on a STOCK flywheel? and why did half my disc shatter?
