If the A/C system is fully charged with R12 and other parts are clean and proper, there should be no reason it can't chill you out of the cabin, even on a humid 90 degree day. Those systems were more than capable if the condenser is clean, and the correct refrigerant is used. I get 38 degree air out of the ducts on my 1977 T/A during a hot day.

I purposely looked for a non a/c car way back when I was looking for a classic car. I know I'm not driving it everyday so in the summer I don't mind just driving with the windows down. I don't like the extra clutter and weight under the hood.

It's converted to 134. It blows 42 degrees. Yes I realize R12 would be better. Most of the system has been replaced. My biggest issue is that it doesn't blow hard enough... yes the blower motor is functioning properly. When its in the 80's its fine but I generally have the windows down when its in the 80's. When it gets up into the 90's/100's with the baking hot California sun it doesn't keep the car cool enough. It would probably work better if I lived further north where the sun is less direct. Even though the cooling system has been gone through. It runs warmer than I would like in heavy traffic with the A/C on... Its an old car. I tend to avoid baking sun with that car anyways... I don't want the dash .. etc.. to crack. Guess I'm spoiled with modern car HVAC systems.

Just curious. On a 2nd gen F Body, there is a large foam seal in the main ducting for the dash. The foam can disintegrate, and air can leak around the opening, lowering the intensity of the air through the vents. Also, the main duct under the glove box, which this seal is attached to, is a known weak spot, and can crack, leaking more air.

That was a rough test-drive video...reminds me of the roads here 🙄

Everyone complaining about all the part swaps poor buggar. Maybe this one will be a down-to-earth sale at least...

All about "stance and looks?" Ever driven an original car, or worse one with poly bushings with taller wheels with no sidewall... over any bumps?
The stock suspension is SOOOO Slow, the car is on the next bump as the tire is just coming down from the last.. Result.. 1 ton truck ride...
GM Never put bigger wheels on these cars until they installed a much faster Strut system.
One way around this is to put on Global West Del A Lum Bearings in the control arms so they move freely, and use a good gas charged shock, OR
put Qa-1 adjustables in your converted ( to Global west bearings) control arms.
stiff suspension beats up the car and my back....
