Do you use your A/C

I won't even consider buying an old Mopar unless it has factory air. My 71 Polara in my avatar has R12, I've driven it 10,000 miles the last few years. Went on our Tour Nebraska this summer, 950 miles. Then my 67 Dart has all the original AC with R12, ice cold. Then my 69 R/T doesn't have air- only drove it once this summer. Back when we were younger. beer used to keep us cool, but that doesn't work any more.
I do quite a bit of driving on the interstate at 75-80 mph. When I have the windows down, it just beats the hell out of me.
