 Brass contact are important imo especially if you have a high voltage coil. Even then, there's no guarantee!
Ya, I actually called Mac’s to see if the cap they sell with the brass contacts is made in the USA. It is so I got 2 of them. They also have one with aluminum contacts that is made in USA too. The one I have on the car is the aluminum one and it does have a made in USA logo on the inside, but I ordered the brass.

 Good choice imo. Always good to have spares as well these days.
Talking of spares, I just put together another SPA-T variable ratio Saginaw 800 PS box (gear) to have on the shelf in case the current one f's up. It will probably be on the shelf for as long as own the car, but!!!!

Took a couple pics. I actually see 3 small cracks by the electrodes and my rotor doesn’t look to good either.

Time to replace both. I think we all tend to forget this little item and the trouble a small crack or burn can cause. It could easily leave you on the side of the road...… cursing of course.
