Thanks, Pinto5.0. Looking around Oreilly's, it appears the 86-93 Mustang NA 2.3 5-speed clutch disc should fit, not sure about the pressure plate. Make sure it is the 8.5" OD and not the larger turbo clutch disc. For some reason they do not list the clutch disk without the pressure plate. When I did my 2.0 to RAD conversion back in the mid-70's, I could not find a disc to fit the stock clutch (this sure would have made it easier/cheaper).
