+1.
1993 still came with R-12. Now, it MAY have been retrofitted if it's had any A/C work done through the previous years. However, if it has been retrofitted to r-134a, the technician was supposed to place a label under the hood to inform further technicians that the car has already been retrofitted.
For the OP, in case you might not know. Retrofitting is the process of converting your A/C from R-12 refrigerant to run on R-134a refrigerant because R-12 is environment unfriendly. It's standard procedure. All the recharge kits sold to the public are for R-134a, as you need to be ESCO certified to purchase R-12 (I believe)
