Condenser and drier recommendation

Looking for a recommendation for a AC condenser and drier for a 66 el Camino/Chevelle. The 66 I bought didnít come with these. However, it did come with this compressor:

Re: Condenser and drier recommendation

Looks like a used compressor. Any history on it? Me personally, I'd get a new compressor and not take any chances on a used compressor. Does that compressor fit your bracket mounts?

A parallel flow condenser is the best choice.

I like receiver-driers with a sight glass in the top to view any bubbles in the refrigerant flow. Bubbles, combined with the use of AC pressure gauges, are good diagnostic tools for how much refrigerant exists in the system.

Re: Condenser and drier recommendation

Here is what I know. I like to play with the old style C-60 G.M. A/C units.
I get 38 degrees out of the center vent on my 1970 ( Fake / Fraud ) SS 454, 70 Nomad Sta. Wgn. First I wanted to keep it looking close to a stock 70 A/C unit.
I sent my P.O.A. to Florida and had it set for R-134.--- #2--- I replaced all the A/C hoses with ( look like O.E.M. BUT R-134 compatible ). ---#3--- R-134 compatible dryer. ---#4--- Find the largest Parallel flow condenser that will fit. I also have from the Fla. guys a modern 10 Cyl. R-134 compressor (painted black). Charge it with 80% of the Org. R-12 Charge. Why ,, So much changing of parts?
.................................................. .................................................. .......
HOSES-- R-134 Molecules are much smaller than the R-12 and will bleed through the Org. style hoses, And the front SEAL of the old style A-6 compressor, unless you can find a new R-134 front seal. ( using org. hoses, and the A-6 you may have to recharge every 1-2 years)
DRYER-- Needs a different medium for R-134.
P.O.A.-- R-134 operates at a different pressure than R-12.
CONDENSER-- R-134 operates Appx. 20 % hotter than R-12. Need more Sq. Inches of cooling area.
EVAPORATOR--Your call, WHY? Can you guess how many Cu. Ft. of ( Dirt, Bugs, animal droppings, leaves, Etc,Etc.) air has gone through this unit in 40-50 years.
All of the above will give you KOLD air. Option # 2 Change out your old C-60 unit for Modern style R-134 G.M. unit. They work very well.
Option # 3 THE BEST OPTION on the planet,,,,,,, BARR NONE.
Rebuild your stock C-60 and shoot it with, Old Style "" R-12 "".
The old C-60 rebuilt along with R-12 is the KATS AZZ. The statement you just read about R-12 is " FACT " not fiction, And can not be DENIED !...

P.S. My one owner 1970 LS-5/ M-22 El Camino uses R-12.
69-72 evaporator remove. Pull the engine side of the suitcase and it will come out. no need to remove the blower side of the suitcase. I just changed mine, Thanx John Souza, MD.
