A/C question

Just got finished with ac in my 73 satellite and i think it made my daily drivers a lot more fun to drive rolling down the road with the windows up sun glasses on jamming the stock amfm radio. watching people drive by in there econo boxes with windows down and no air just dying kills me. I would say if its all there refill and use it. r 12 is not illegal you just cant buy it without a mvac license and you can get that online doing an open book test for 19.00 dollars at mainstream engineering
