1971 C10 Emissions question

[Billyzack]

Hello all, I just picked up a 1971 Chevy C10 with an inline six and have a emissions question. I live In Arizona so I am required to run the truck through their money making emissions checking system. My question is does a anyone know what equipment this truck should have on it. It has a PCV, it has a vapor canister, no catalytic convertor as they weren't required until 1975, other than those things, does anyone know what else may be required. I hate going there and paying and waiting just to have them tell me something is missing and having to go back and do it all over. We are not as strict as California as far as labels etc., I just can't find anything online that breks down what is needed. Thanks in advance, Billy
