Detailed Product Overview

The WAI DST1893 distributor is engineered for direct replacement in compatible GM rear-wheel-drive and front-wheel-drive applications from the 1970s and 1980s.

WAI manufactures this distributor as a complete new assembly, using all-new components and verifying performance before release. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 1974-1979 Oldsmobile Cutlass Supreme, 1977-1979 Pontiac Firebird, and 1982-1987 Buick LeSabre applications, among others. Part number DST1893 is also referenced across multiple interchange numbers for service matching and catalog lookup.

Common Issues This Part Can Address

• Hard starting caused by a worn distributor assembly
• Misfire or rough idle from inconsistent ignition signal

Installation Notes and Tips

Verify engine application, vacuum advance configuration, and gear compatibility before installation. This distributor is listed for vacuum-equipped applications where noted in the fitment data. Transfer timing settings carefully during replacement, and confirm rotor indexing and cap seating before starting the engine. DST1893 is a direct-fit assembly, but final timing adjustment may be required after installation.
