Vacuum advance cans
So, I discovered today that the ac advance in my '77 HEI was inoperable.
It was stamped with 517 18
I replaced it with a functional can i had laying around in an old HEI--the can i replaced it with was 624 20.
What are the major differences in the two cans?
i cannot locate any other part number on either, and I am unable to find a part # cross reference...
