Intermittent total loss of electrical

Not sure what you mean about the cover. The springs are contacting a 'floating' piece of metal that was no longer restrained when I pulled the cylinder out of the switch body. I'm surprised only one of the springs launched. Is there supposed to be a cover that holds it all together? That would make sense. The key action is a little sloppy, so maybe its time to re-key?

I can take another picture of cylinder I removed from my '67 in the next day or two. That sheet metal was crimped into the casting so I didn't touch it. I don't know if its original to the car as the door keys didn't match. With mismatched keys to begin with, I thought it made sense for me to buy new keys and cylinder.
The repo has some slop in it too and I'd have the keys fitted a little better if there was a local locksmith I trusted. I also bought new door locks but not sure I'm going to use them.
Maybe start a thread about ignition cylinder and one of the guys here who knows about such things can provide more guidance. Most people like to have the ignition cylinder and door locks using the same key. At this point I'm so use to using two keys it doesn't bother me...
