I went back to AutoZone to talk to the manager to see if he might know of something avaliable, he went in the back and came out with a typical card with a plastic bubble containing what at first looked like a clutch aligning tool. But it was the tool that Larry described. It contained .75 ounce ot R-12 oil. I thanked him and went back to the location where the A/C stuff was, and now that I knew what I was looking for, I found several other cards of the same thing, same part number, only these contained a full ounce. Not that big of a difference, but I grabbed one of them instead. They didn't ask for any kind of cert. By the way I also noticed 12 oz. bottles of R-12 Oil at Kragens.
Is the 609 cert the same as an EPA Universal Cert?
I'm going to give it a spin in the morning. Thanks to both of you for the help.
