I paid $100 for everything AC related that was on a truck. I got everything but the compressor and brackets for the engine. If you are doing this swap take the old receiver/dryer even though you are going to replace it. I'd rather mock up a throw-away item then mess around with a new one and exposing it to the atmosphere. I ended up paying another $100 for a full set of brackets. The compressor is off a '71 Monte I junked a while back. If I ever get my engine back from my soon to be former machine shop I'm going to finish the installation with a new receiver/dryer and R-134A. I already made the adjustments to the factory POA.

Obviously I think you should go with original and somebody would want to buy your AC stuff. I'll have $300 or less into mine when I'm done. Remember too that a truck cab is quite a bit smaller than a car's passenger compartment. R-134A should do just fine cooling it down. Save your R12 for your cars.
