There is plenty of R-12 on ebay. I buy it all the time. Keep looking for the best prices...usually between 25-40 can. Now, if you need a big canister of it, that can run hundreds of dollars, so you have to decide what you personally need. Most of our-era cars take 2-3 cans to fill, but earlier cars may need more. I have no idea, but you probably do. Cheers!
I'd like to have a full tank...since I know I'll need it in the future. But for now all I'm trying to do is scrap enough together to top off one car and totally fill the other. Might just have to do the ebay thing for that at this point.
My son is coming here tomorrow from NC,I gave him a 30 PDS can of that stuff.If he still has it,I'll ask him if he wants to sell it.Bruno.
