I just threw some new, original caps away. I took them to the last swap meet and tried to sell them for a few bucks each but nobody was interested. One guy wanted to know if they were for a dual point distributor. I have no idea if dual points used a different cap, not sure why they would so I told him I didn't know.
The cap and rotor are different between the stock single point and stock dual point distributors, the dual point caps have the carbon from the coil wire going to the flat rotor. The single point caps have a brass pointed thingy( CRS proper name (
) and the rotors have a flexable thin blade that pushes up against the brass contact
As far as the Accel caps, the new ones, both types, are smooth inside now
