New '72 240Z owner trying to get it safety inspected. Recently "rebuilt". The state inspection guys tell me I don't have a smog canister(???) I have never heard or seen anything about a smog canister. Courtesy Nissan knows what it is....$360!!!! Fill me in guys and tell where I can get one for cheap. How does it connect? Oh yeah..L28 block, E88 head, 280 electronic ign, '71 SU carbs, stock airfilter.
