Did People Tint Windows in mid - late 70s?

My buddy had a 1968 Coronet 440, about 15 years ago and it was tinted and looked good (I thought anyway!) I think it depends on the car and the color but I am going to paint my 71 Challenger black with black R/T stripes and black shaker and tint the windows very dark,it will look pretty menacing, nothing like a blacked out Mopar shaking windows to send the chevy kids screaming to their mothers!!!!:sad2:
