What is the year of your flywheel?
What is the diameter of your clutch disc?
NAPA does not show a pressure plate by itself. Most likely you will only be able to buy a clutch assembly as a set. If you know the part number of the pressure plate, NAPA might be able/willing to look for it.
Your first consideration/problem in even finding an assembly is that the assembly will have to match the diameter clutch/pressure-plate that can be attached to your flywheel.
The parts suppliers probably sell the set, instead of parts, because the clutch and pressure plate have to match the flywheel, and the release bearing has to match the style of the pressure plate. Purchasers and counter-people would regularly be confused/mistaken in trying to match up old/new individual parts in the assembly.
O'Reilly sells an 10" assembly at a reasonable price.
