FINALLY the Daughters Duster will freeze your nipples off. I will try to limit my rant of aftermarket parts. The POS aftermarket expansion valves flood the evaporator and I went through 3 compressors where the super heat was totallly wrong on the valve and flooded liquid into the compressor failing the reed valves. Bought NOS reed valve plates and a NOS expansion valve (yes it is R12 BUT THAT DOES NOT MATTER). I plan to tighten the spring in the valve on turn in to compensate for the R134A with this valve but all the problems are gone and it is flipping cold 32F on the road on a 75F afternoon. Oh and this was no more than an O’Rileys rebuilt compressor.
