Differences between 273 Commando Silenced Air Cleaners?

I just was curious if all cars produced in LA had CAP whether they were sold in California or not. What all states were the California produced cars sold in?
TMM, for all cars produced in California the C.A.P package was mandatory. What I've heard of is that cars assembled in CA but to be sold in Oregon or Arizona got that package too. Otherwise they could not drive the cars on the rail wagons or on the trucks in L.A.!
I have heard this from two different sources but I don' have any documents to prove it.
