An R12 system must be retrofitted to be made compatible with R-134a.
No, there is retrofitting required.
No. It is illegal, will not work properly and R12 Freon is not available for the public to buy anyway.
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).

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.
