Thanks for the pic, in research phase of AC/heat systems now. Really mostly to get windshield to defog properly and AC would probably be nice on drag week.

Hry Quick, I remember that weekend,,,all too well, I was in the next to last pair when they called it for the night,,don't want to do that again!
