The a/c in the 67 isnt' cooling as good as it used to and I was wanting to check the line pressures and make sure it isn't low on freon. I converted it over to 134 a few years ago. A friend of mine at work has a set of gauges and we're going to hook it up tomorrow. Is it supposed to between in the 200-250 range on the high side and ~30 or so on the low?
