Is a catalytic converter required in CA on a 1983 GMC C3500?

somebody on here had to get tested ona 76 3/4 ton, but being a one ton could be different, although i think they usually group the 3/4 an 1 tons together....you can get high flow cats alot cheaper now....

Yes, California tests emissions (back to 1976) and requires catalytic converters on all vehicles that came with them from the factory.

So then, Can you tell if the truck ever had a cat on it? is there a shield on the floorboard? is the sticker still under the hood that shows the original polution setup? The dealer may be able to run the vin and tell you what stock is. AIR,EGR,CAT,lean run w/sealed carb etc.
