Dual point distributor ID question

KosmicKuda said
Replacement vac advance pods have different total advances available. There should be a number stamped on the flat linkage arm. IIRC it's advance in crankshaft degrees but don't quote me.

Where's @Halifaxwhen you need him.

For regular Mopar distributors. Those vac advance units for the old dual points are next to impossible to find.
