In a nut shell; the CA dizzy is unique.


PET seems to indicate that the 1978 CA dizzy is used on other cars.

The 930 602 101 07 distributor looks to be original fitment to 930/61 (1978 US) and 930/62 (Japan) motors.

The 930 602 101 08 distributor is sohwn as fitting 930 61/62/63/64/65. 930/63 is 1978 California. (930/64: 1979 US, 930/65: Japan).

It all changes again with 930/66 (Euro/Canada) & 930/68 (USA, no California model), but all distributors after 930 602 101 08 use the same part # for the vacuum unit.

I guess what would really tell the story is graphs/documentation specific to the 930 602 103 00 (930/66) & 930 602 104 00 (930/68) dizzies.

If you look in your shop manual you will see that one side of the pot is connected to the vac source under the throttle plate while the other side is connected to three sources; the air pump, boost, and back to the vac source under the throttle plate.
Yes, I saw that. I note that this is the same way that '80 up RoW cars are plumbed. I gather that '86 up US cars are precisely the same.

So it looks as though, post-1980, everything moved to the way they were doing CA distributors in 1978, at least until they did whatever they did for the 930/66 and 930/68 motors, yet to be determined.

They dropped the CA-only with the 930/68, so it clearly was a 50-state model.
