Factory Air Conditioning Upgrades

[rustaddict]

I have a 71 Cheyenne that I think I'm about to fix the factory Air on after years of ownership. I'm missing the compressor and hoses. I see that all they seem to offer now is the reman A6 compressor and an aftermarket one that bolts up in the factory brackets. I guess there's also the alternative of Alan Grove type brackets and the aluminum sanden type compressors. I once had a catalog that offered a kit that had an evaporator and dryer that looked like it came out if an 85ish Silverado that was designed to do away with the poa valve and expansion valve. Which is the best way to go?
