By 1983 the CARB required more info to be displayed I would imagine, the earlier plates affixed to the B pillar didn’t have to address things live Catalytic Converters.This is the first CA import sticker I've seen like this. I usually come across the smaller metal b.a.r. stickers in the engine compartment or door jamb on the grey market cars. View attachment 145313
It’s a California thing.My CSi escaped that when it was imported in 1991.
