I'm converting to 12 volt on a 55 1st series pickup. I have a new wiring harness ready for the 12 volt system. I can't find any reference that talks about what to do with the coil and distributor. What are the modifications needed for a coil and distributor. I'm planning on getting a new distributor and coil. Is that all I need to do? What about the spark plugs? those probably need to be different. What size should I get? Anybody done this to a 235 before with good success?
