NAPA still sells 12-oz cans under part number NFR R12CAN for $60 - $90 per can, depending on the type of account you have with them. They currently have about 600 cans in stock between the various Distribution Centers, with almost 100 just in Phoenix (go figure...). That works out to a cost of $80 - $120 per pound. You can also get an R12 30-pound bottle under part number NFR 209514 for $1550 - $2600 depending on your account, which is $52 - $87 per pound.

Or check out Craigslist- there is always somebody cleaning out their basement/garage with a few cans- going rate about $30.

Check with HVAC guys in your town. They all have it. And they all know how to charge a refrigerator unit.

I have converted many cars from R-12 to R-134 and all the conversions were successful - they blow just as good as R-12. 40F vent temperature easy. On my 93 truck, I have a bypass switch to the pressure cycling switch and I can get the vent temp to 34F - that is a typical summer day. So much cheaper and easier to buy in your local store - flush your system to get most of the original mineral oil out and then instead of PAG oil, use Ester oil which mixes well with both PAG and original R-12 mineral oil.

Corvette R12 systems typically take 3 pounds 4 ounces, which is just over four 12-oz cans.

R-12 is a better refrigerant than R-134 and will work better in our already marginal A/C systems and runs at lower pressures.
If your system doesn’t leak, the cost of the R-12 is peanuts compared to properly retrofitting your A/C to run R-134.
