Yes, I actually need to take a '75 C3 through an exhaust emissions test. No, I don't live in CA. In 5 or 6 TN counties, emissions testing is required for all vehicles 1975 and newer. So, what should this thing emit? I have access to an emissions analyzer, but need to know what I am looking for. If anyone can point me in the right direction, that would be great. I just want to make sure this thing will pass.
