Product Details

WAI DST3690 is a complete ignition distributor built to meet or exceed OE manufacturing and performance requirements. It is manufactured with all new components and is intended for vehicles that use a vacuum-style distributor configuration. The included cap and rotor simplify replacement and help restore proper ignition timing and spark delivery. If you are servicing a Dodge Ramcharger, Chrysler Newport, or Dodge Dart, the DST3690 provides a straightforward replacement option that matches the original application.

This part cross-references select OE and aftermarket numbers, including 3656859 and 3755037, for the same application.
