Anyone ever disassemble a distributor - need help

Any of you ever swap that slotted mechanism ? The bottom of spare distributor says 11 degrees. I don’t know if all Chrysler small blocks are degreed the same ? Or if the degrees changed from different size small blocks, year, model, etc ? I’m bout to remove the one on the car in next few hours.
Swapped 'em, welded and brazed and filed 'em.
No they are not all the same.
That's 11 degrees of distributor advance, 22 at the crank. It will be a little less on the engine unless running points.

The amount of advance depended on the engine configuration and what clean air package it had, if any.
11 in a electronic distributor is nice for a slightly hotter cam and no pollution control.
