I went through the A/C system in our 1964 Dart GT (with 273 V8) this weekend looking for a leak using soap bubbles and an electronic detector. The good news is the hoses, evaporator coils, and condenser coils are good to go. I found leaking schraeder fittings that I replaced, as well as a couple of joints that needed to be tightened, so the majority of the leaks are addressed with minimal effort. The only leak left is in the drier, and specifically in the sight glass on top of the drier (pictured below). Judging by the compressor and evaporator/blower under the dash, this appears to be a Mopar / dealer-added system.
I've checked with a couple of the vendors for A/C parts (classic industries and year one) but they don't seem to offer them. Any idea where I could find this drier? I'm guessing the sight glass may be serviceable, but best practice is to replace the drier when opening a sealed refrigeration system. Any vendor recommendations would be greatly appreciated.
