This should NOT be done... You will contaminate the whole system and have to repalce everythig A/C. The A/C will not work if it is mixed. Very expensive.

R134a.
R12 was in use up until the 90's when R134A was introduced. I believe R12 was phased out at the end of 94, And R134A took it's place from 95 on. I hope that's the answer you're looking for.
Chemical instability of mixing a CFC and HFC together increases the risk of fireExcessive system pressure resulting in damage to or destruction of AC system componentsImproper lubrication of the compressor since the R134a won't carry the oil used for R12 systems properly
An R12 system must be retrofitted to be made compatible with R-134a.
2 pounds of r134a. Not r12.
No, there is retrofitting required.
