I have a late 60's GM (Chevy?) distributor that I converted to a dual point breaker plate back in the 70's to put into a 69 Dodge 318, but never used it.

It has a brand new cap, rotor, 2 sets of points and condenser.

Without pulling my 1962 F85, 215V8 dizzy and making comparative measurements of everything - can anyone tell me if the above components were same dimensions for most or all GM V8 distributors?

Im pretty sure V8 Olds dist were same for big/small from 60 to maybe 70 something but Im not sure about other GM engines (V8 only of course). (Dont have a Hollanders)
