Steps To Retrofit The R12 To A R134A System: Locate the receiver dryer and check if all of the R12 has been bled out. Remove the low-side fitting that’s located on a pipe below the dryer and swap it with the conversion part. Mount the conversion fittings on the new receiver dryer.

There are "drop-in" R22 replacement in the market like R421a, R422B and MO99 (also MO29 for low-temp applications) but NONE of those can be mixed with R22. The bottom line is: If your system lost more that 15-20% of the total R22 charge you may want to consider to evacuate (with a recovery unit) the residual gas and recharge with a replacement.
