The plugs don't match up. Maybe a 240 six cylinder dist would work . Did they offer a 300 six in 76??? or was it still a 240???
He needs to respond to my question first. I want to keep things simple.
To answer your questions though, Duraspark 1 should be gone by 76 (someone can correct me if I'm wrong). All Durasparks have a hot-in-START spark retard function; the degree of retard varies with grommet color. Elevation does not tie in to the common blue-grommet Duraspark 2 module.
Back to the main topic, OP please post a pic of what is coming out of your distributor, a shot with the cap off would be nice too.
