As gashog posted above it would have come from the factory with the R12 style freon, convert it over to the R134 style. The conversion kit and R134 put together will cost much less than just the R12 if you're luck enough to find a shop that still has any.
jr32560, if I remember correctly it's about 85% as effective as R12 but you'll never notice the slight difference.

This thread Is giving me the idea to put my cans of freon 12 on Craigslist for sale, I have over a case and I could use the money. 
If I were you, I would convert it to 134 freon

BTDT...r134a works quite well, but don't do the conversion yourself. If the r12 is gone, you have a leak, so let the pros handle it and get your pressures correct. Otherwise you'll just be p***ing away your money. It cost me $375 to have my '93 done, and that included replacing the pressure switch, which was bad and caused the leak in the first place.

Part of the change over process is to change the oil. R-12 compatible oil isn't necessarily compatible with R-134a. Checking for leaks, flushing the system and putting in a new dryer and orifice tube then recharging the oil and freon load is the best way. A shop can do this in a few hours for you.
