Working on electronic ignition conversion for HP273 dual point distributors

There you go. Original caps were black without a vent. Contacts were brass, I'll second using dielectric grease on the plug wire sockets, not sure I'd use it anywhere else.

Oh, that's interesting... I'll be sure to mention it to the "your cap should be tan" guys, ha ha!
Btw, my 30 years in storage plug wires looked great, but were stuck like someone glued them on at the cap and plugs. Tore a few in half trying to get them loose!

Definately greasing ends of new ones, curious about the expert advise for inside cap, very aprehensive though... maybe just a light film on the metal?
