I assume that your car has 4-wheel disc brakes, and the parking brakes consist of small brake shoes which make contact inside an enlarged hub area of the rotor. If NAPA has them, I would just order them from there. It's a twenty-year-old car, and these are relatively obscure parts.

Do you need the parking brake shoes? Was the parking brake on accidently for a period of time? Normally these shoes will last the lifetime of the car, as they are usually only applied after the car is stationary.
