At this point in time if it did take R12 it needs to be retrofitted to 134A. Your right in the transition years between R12 and 134A vehicles.


You can buy R12 on Ebay. but you need have to your AC, license. 30Lbs $800, much larger molecules then 134A ;1,1,1,2-Tetrafluoroethane; Freon 134a; Ethane, 1,1,1,2-tetrafluoro-; Halocarbon 134a; 1,2,2,2-Tetrafluoroethane; HFC-134a;


Ey Auto, what license are you talking about?


EPA, Section 608, 609, Certification plus your Lab research, Just Check out...EPA required Certs and licenses. HFCs were used to replace ozone hole-depleting chlorofluorocarbons in the 1980s, but as part of the Obama administration’s Climate Action Plan, the EPA is requiring them to disappear from air conditioners, restaurant refrigerators, foam blowers, vending machines and aerosols in favor of more climate-friendly gases. In the grand scheme of greenhouse gases, HFCs don’t amount to much, but they’re very potent. Fluorinated gases, including HFCs, make up about 3 percent of total U.S. greenhouse gas emissions. The EPA measures their potency based on how much they’ll contribute to global warming while remaining in the atmosphere over the course of a century, a measure known as “global warming potential.” HFCs range between 90 and 12,000 times as potent as carbon dioxide. VERY, useful for earning $$$


HMMM must be a State thing, nothing like that here, you can purchase 134 over the counter.
