[V8] Tools for A/C work

[Scott DeWitt]

I would avoid any R12 alternatives as many aren't fully tested, aren't 
goverment approved, and difficult to come by locally. Many are blends of 
refrigerants, which tend to seep out of the system at different rates. A 
R134A conversion can be as simple as replacing the oil with R134A oil, and 
change the drier. Type 44 driers can be had for 25 bucks.
