Reply to "4 row condensor vs. stock 3 row"

Eric,

I would suggest you reconsider your intent to retain the R-12. Yes it is available, and yes it does a better job than 134a. But, sure is damn expensive when you go through normal channels. And getting harder and harder to find shops that still do the work. Since you will have a new compressor and drier, maybe condenser too, and all new lines, it would be the perfect time to flush out the old R-12 system oil that will be remaining only in the evaporator and do the switch to 134a. Whatever you do, make sure the hoses are the newer barrier type for yours, or a future owner's, 134a conversion. R-12 or 134a, you might add a high pressure cut-out switch to the system at this time, too. You can wire it in to drop the compressor clutch out if you ever get the known high-speed air starvation at the condensor problem that can cause temps/pressure to rise enough to blow out hoses/fittings. Here's to cold air at the vents which ever way you go.
