I don’t know why so many people act like r12 is gold and not obtainable. It’s easily purchased on eBay. Buy a few cans and recharge your car. If it leaks out again, find the leak, fix it, and recharge your car by weight.

I’ve done the r134 conversion and it’s ok at speed, but is useless in traffic. I don’t have much experience with drop in substitutes but generally more of a hassle than it’s worth.
