R12 is readily available on Facebook marketplace by the can or cylinder. Most guys are asking $40-$50 per 12-14oz cans, so its not cheap. You will need about 60oz for the average '60s based system. If your system has not run for some time I would recommend flushing the system and pulling a vacuum to be sure it is not leaking. Replacing the dryer is also a good idea. All in all, just standard maintenance to the system. Converting your system to run 134a is much more involved and costly. Nothing cools like good old R12 in an original system.
