My 1969 Olds Cutlass convertible needs a better heater box. My old one is pretty eaten up.
I’m looking for a better one? Any one out there have one for sale?
Agreed, roughly 1970 was the turning point, most likely. More '69 and before cars did not have air, and more '70 up cars had air than did not. It was a big extra expense, back in the day. Frankly prefer the simplicity of an older non air car.
