‘61 Newport that is new to me- sorting her out and trying to identify some parts….

I know you're the distributor guy, but aren't the cast-iron distributors different?
My 65 413's dual-point takes a different cap like this one. I presumed it to be the correct/original item.
I tried a later 'standard' cap and it does not fit, the clocking tab on the dizzy does not fit the notch on the later cap.

???

Thats the prestolite style. The others have a notch in them for a tab on the vac advance to fit into.
