EP-1635A Electronic Distributor for Chevrolet Astro El Camino 4.3L V6 — Variant

The EP-1635A is a variant-configuration electronic distributor for the Chevrolet Astro van, El Camino, and GMC Safari with the 4.3L V6 TBI engine. The EP-1635A covers earlier production years (from 1985) and a different connector or housing specification variant than the EP-1635. Together, EP-1635 and EP-1635A provide complete coverage of the 4.3L V6 TBI Astro/Safari/El Camino distributor range across the entire 1985-1994 production period.

The GM 4.3L V6 went through several minor distributor specification changes during the Astro's production run, resulting in the need for two catalogued variants (EP-1635 and EP-1635A) to ensure correct connector and housing fitment across all model years. Verify the OEM number on your existing distributor (1103836 or 10495798 for EP-1635A) to confirm the correct variant.
