distributor types...

Ok, so now for another round of questions that I should already know the answers to:
Does anyone have a picture of the cap and rotor used in a prestolite iat-4405 type distributor? The ones in/on mine don't look like the ones Napa carries, and has obviously at some point been grinding on the cap despite the fact that it runs fine. The distributor is somewhat freshly rebuilt, (or at least had new points and condenser installed), so I wonder if maybe someone just put the wrong parts in it? I was also wondering if anyone makes an electronic kit like the pertronix for the prestolite?
