distributer cap mods?

I,ve had the same dizzy cap on mine for 4-5 years. I belive it's a NAPA cap
and rotor. Has a vent built in. No problems. I'd stay away from those Wells
brand stuff. Get a good one from a major store. Those chain stores like
Autozone, Checkers, O'Reily's get a cheap manufacture to build for them.
