".....Just one more question. Are you changing the refrigerant over to R134?...."

Probably. For the last several years I'd been using "Freeze 12" which was a drop in replacement for the R12. Unfortunately that has gotten almost impossible to find and expensive when you do find it. I re-did my wifes El Camino to R134 last year due to cost and availability and unless I can find a good deal on R12 or Freeze 12 I'll end up using the R134 in this one too. On a side note, even after sitting for the last 10 years, the AC system was still holding pressure on the little truck.
