Re: 77 304 v-8 w/prestolite, how to replace?
Sorry that I was of the board for the weekend, but my Grandmother passed away wednesday and I attended the memorial yesterday.
In relevance tho, I too have a '77 CJ-5 w/ 304, and I have performed the TR upgrade succesfully.
What you need to do is go to the local parts store and as for a distributor from a 78-80 cj (pick one, any one) and also get the module and coil. They'll want a core on the old distributor, bring it back later so they can't compare them. They will take your prestolite as a core return on the duraspark. Then get the connectors from ANY late 70's early 80's ford, mercury JEEP junkyard heep. Then wire the harness as Teamrush himself laid out in his 'test' harness. The trick to remember here is that the red (+) wire to the coil NEEDS a resistor. I used a wells F795 and its doing fine. You could use the resistor wire (uncut) that the 78-86 Cj's used, but the resistor goes in alittle easier. Other than that, the upgrade is as advertised. If I left something out, or you have more questions, e-mail or post them, I'll be 'round.
