And to add to my confusion.
For the 1968 parts book, the distributor should be 2875358, which I believe is a single point Chrysler unit (not Prestolite).
For 2875358, the correct vacuum control should be 2875096.
Attached is a FSM photo of Chrysler and Presolite parts breakout. My 2875358 looks like the one on the left (Chrysler) but 2875096 vacuum control looks like the one on the right (Prestolite).
So is the FSM wrong or parts book wrong?
The Chrysler vacuum advance is as shown with the tang to fit the slot on the cap and a pressed pin on the arm for the breaker plate,the Prestolite has no tang for the cap and a hole in the end of arm for the pin located on the breaker plate.The design of the advance changed in 1970 but the configuration is the same.
