Detailed Product Overview

The WAI DST1845 distributor is designed for direct-fit service on classic Chevrolet and GMC platforms, including C10, K10, K20, G20, P30, and related models, as well as select Buick applications. This part number is built as a complete ignition distributor assembly with all-new components, making it a practical replacement when restoring spark timing control and ignition reliability on older GM vehicles. The DST1845 is also referenced by part number 1103238 for the same application.

WAI manufactures this distributor with a magnetic pickup design, a 13-tooth melonized steel gear, and an aluminum housing to support stable operation and OE-style fitment. Because the ignition coil, cap, and rotor are included, the unit is prepared for installation without sourcing separate core ignition components. This makes the DST1845 a strong match for Chevrolet C10 and GMC K2500 service work where a direct replacement distributor is needed.

Common Problems This Part Can Address

• Hard starting caused by worn distributor internals
• Misfire or rough idle from inconsistent ignition timing
• Weak spark delivery from aging cap, rotor, or coil components
• Distributor gear wear affecting ignition synchronization
• Service delays when replacing multiple ignition components separately
