You have one of the early MSD distributors before they started zinc coating them. I believe you can call support, and they will replace it for you. That causes ignition issues and is a known problem.

You could disassemble the distributor and clean it up, shoot it with a coating, but it could effect the reluctor and pickup. (Don't spray the pickup). I still think they will replace it though.

Not sure I would trust those wire diagrams from that website, I would be looking at the factory diagrams, which are available, the factory service manual does have diagrams, and is basically a very good reference, pays for itself in time.

I wouldn't worry about the diagram, since everything is working. They probably used a generic or 'chevy' diagram.

The 'dual crimp' wire ends are fine, and prevent the core from breaking during installation. If you're making them yourself, push down on the core with a needle or something so it is captured during the crimp, and you will be fine.
