Installed everything on Saturday. I went with Belden Premium 7mm wires and Echlin distributor cap with brass contacts and Echlin rotor. Like you mentioned, the rotor was a little bit wider than the old one, but the part number lists that one for 318 and 360 engines. I had oem Mopar wires and cap on the van that were put on in 2002 and they seem to be a lot better built than what I installed, I guess time will tell. The old distributor cap showed corrosion or arcing on a couple contacts and the plug wires had green build-up on a few of the connections. I still need to get the carb worked on, the float is messed up.
