Back in high school, my 68 Charger caught on fire in the exact same location yours did. Luckily I wasn't moving yet and had just started the car. I smelt something funny after the car was running for a moment and I shut it off. I figured a wire was burning against the header. So I calmly walked around and opened the hood... that's when I saw what you did and freaked! I didn't have anything to put it out with. I started slapping at the flames with my hands (stupid, I know) and thought to remove my shirt to smother it and at that moment a neighbor dragged his garden hose over and put it out. He was in his robes, guess I caught him watching TV on the couch. I replaced the distributor, plug wires, coil, and fuel line. I've never liked how a DP fuel line makes it's connection directly by the distributor. So for the fuel line, I bought brass fittings and made my own to reduce the risk. Oh ya, I have a fire extinguisher in my cuda now... mounted to the roll cage. Glad you got that sucker under control!
