No, there is retrofitting required.
It's only Freon if it was manufactured by DuPont, but to the important things... Your 89 would have had an R12 system from the factory. You can't use R134a in an R12 system unless you do at least a partial retrofit (evacuate all the R12 and compressor oil, replace the orifice tube, replace the accumulator, replace the hose connections, add PAG oil and R134a).
An R12 system must be retrofitted to be made compatible with R-134a.
No, you should not mix R134a and R12 refrigerants in a 1993 Buick LeSabre or any other vehicle. Mixing these refrigerants can lead to system damage and reduced efficiency, as they have different chemical properties and pressure requirements. If you need to convert from R12 to R134a, it's essential to properly evacuate the system and replace any necessary components to ensure compatibility. Always consult a professional for refrigerant conversions.
No. It is illegal, will not work properly and R12 Freon is not available for the public to buy anyway.

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.
2 pounds of r134a. Not r12.
