65 Barracuda daily driver
It appears I have found the culprit. What you are looking at below is one of the contacts in the distributor cap. All the contacts were somewhat damaged as well as the rotor. So I replaced the cap and rotor and they came with new wires, so I swapped everything and the problem seems to be solved. I wonder how the damage occurred, and I assume that the car was running when the distributor cap wasn't fully seated? No idea, but I'm glad it's fixed now.
