The EP-2690 is a Duraspark II electronic distributor for the Ford Fairmont and Fox body Mustang from 1978 through 1983. The Fox body platform (introduced with the 1979 Mustang) shared its engine and drivetrain with the Fairmont, and both used the Duraspark II ignition system -- Ford's mid-generation electronic ignition with both mechanical and vacuum advance, sitting between the earlier Duraspark I and the later EEC-IV/TFI system.
The Ford Fairmont and its Mustang/Zephyr/Capri siblings are an important bridge in Ford's product history -- representing the transition from classic muscle car platforms to the lighter, more fuel-efficient Fox body architecture that would carry the Mustang through to 2004. The Duraspark II distributor for this platform is also very widely used as a source of ignition hardware for enthusiasts upgrading older Ford vehicles from points to electronic ignition.
For the DSII swap all parts can be taken from a 1978/79 Ford Fairmont or Futura Distributor: A1 Cardone Part# 30-2690. The Cardone 30-2690 / A1C0/302690 reference and the O'Reilly part number A1C0/302690 make this one of the most recognized Duraspark II references in the classic Ford community.
