Working on electronic ignition conversion for HP273 dual point distributors

My Napa buddy came through, and I got what I asked for;
Echlin ECH AL124 Cap - $17.00,
ECH AL125 Rotor - $6.49.
As I was told, they are for "1967 273 Dual point". I still don't know if that means "Prestolite" parts, or that I have a "Prestolite" distributor, but they fit, and it appears they'll work.

The minor downsides are;

1. They're black, not tan
2. No vent
3 Aluminum contacts in cap

I decided to go with them anyway, since they will get me down the road. Realistically, the aluminum contacts should work adequetely, though I would've preferred brass. I'm guessing the vent may not be that big of a deal either. My last cap was tan, but had no vent either. Maybe it will be needed even less since I've eliminated the two sets of points?

I am very glad that I was able to get something that works, at a moderate price, but would've been even happier, had I actually gotten a tan one, with brass contacts, and a vent. I would've gladly paid a little more for better quality. You know the first person who sees under my hood will point and say "hey, your cap's the wrong color!" Doh!

Now for some dialectric grease on contacts, as halifaxhops reccomends! I'm thinking a very light coating to avoid build up of particles? Sounds kind of crazy, but he could be onto something?
