[70 Forest Green Zee]

I believe that cars only sold in CA got the charcoal canister and the 4489 Holley carb. They could build cars in CA and ship them to other states, then the CA emissions were not required which the canister was part of(RPO code NA9) My 70 Z was build in LA and delivered new to Alameda Calf, so my car has the canister and the 4489 carb. Hope this clears things up.
