how about r-500 refrigerant

A friend of mine has a 30 pound drum of r-500. The r-12 has leaked out of my '79 300SD. I know that r-500 has a higher head pressure and is very similar to r-12, but would it cool as well as it did with the r-12 originally? I don't need to hear as to why I should keep r-12. The car holds 2.2 pounds of r-12, then how much r-500 would it take? What kind of pressure readings would I want to see? Haven't gone into details with him yet as to what might have to be retrofitted. Would anything have to be changed to run r-500?
