Restore factory ac or go aftermarket

I went with the OEM pieces on my 69 Dart. I converted to R-134a and it works like a champ. I actually used the 70 and newer WP, pulley arrangement. I had the original hoses rebuilt at a local HYD shop. I know the old RV-2 compressor is a HP eater, but nothing cools like one either. She blows 34 degrees.
