Do you have part numbers for the differences? I never knew there were multiple.

Yes, but I'll need to dig through my parts stash to find the two articles. That will have to wait until the weekend.
IIRC, there are differences in the mounting brackets as well. I believe the CA valve has a shorter bracket.
There is our garden variety huge vacuum canister decel valve on all fuel injected buses.

There is a little weird looking decel valve for automatics with an electrical plug to open additional air when you select "Drive" in the 1975 003 transmission, and I think they got rid of the electrical switch in 1976 with the 010, but they share this sort of fuel pressure regulator look:

There is a high altitude decel valve which is designed to require lower vacuum signal to open sooner because it is already rich up there at high elevations.

One more decel valve for CA 1979.

The 1975 FI bus had 5* ATDC retarded timing too, and with an automatic, it needed a blast of air if you selected a gear from neutral.
