If they don't sell to E150GT, I would like to be next in line. These sell all the time on FleaBay. R-12 "Freon" or refrigerant does not go bad, go stale, or lost any of its mojo while in the can. So, if the can looks funky, rusted, no problems. One needs a 608 cert. license, however, to legally acquire these. I can scan and email that license to you if necessary -- got mine over a year ago.

Thanks !
