Sorry I can't help with a condenser (maybe look for a mustang one). I have used enviro-safe as a better substitute. It runs at a lower pressure, so it's easier on the compressor. R12 is nice if you can afford it. It's flammable, but we are driving around in cars with a gas tank for a trunk floor, so that's no big deal for us wild risk takers. Try ebay if you are interested.
