I am running the Aeroquip stainless lines.
I have a R134 condensor, compressor, and receiver/dryer and an R-12 evaporator (so I have both styles of fittings.
Took a bit to figure out what to order, but it all went in great. It sure was nice when I re-routed the condensor lines when I put in the new shroud.
Only glitch I had (have) is that the surface of one of the fittings seems to have faded. Must be a crappy batch of stainless or something like that.
Some pic's of that project are up at:
