I am looking for reference manuals that list or not list smog equipment for a 72 blazer. when i got the blazer it did not have any of this stuff. If i can get enough info i'm going to court. anyone know how to determine where a 30+ yr old vehicle was purchaced?? i also found a statment that all 73 and older vehicles are exempt from all smog test/inspections, but also states that if it was present it should remain there /forums/images/graemlins/frown.gif. thanks, ARQ.
