My personal opinion about your options;
Rebuilt Injectors: not recommended
Replace with original injectors: Definitely not recommended, If you could find new original injectors for your 1992, they are not ethanol tolerant. Ethanol blended fuel is likely the cause of the injector failure you are experiencing now.
Recommended fuel injectors: Recommend FIC Injectors. Appearance is very close to the originals. excellent injector.
