How To Charge the AC On Your Dentside F 150

I decided to see if I could put a vacuum on the air conditioning system of my 1977 F150 and charge it up. The air conditioning hasn't worked in well over 10 years. My dad had charged the system with 134a years ago and he said it worked fine. But after sitting for so long, it had slowly leaked out. Instead of replacing a bunch of parts, like the dryer and hoses, I decided to try it as it was to see if it would work. A month later and it's still cooling!
