I've been scratching my head about how to connect anything to the low side valve on the body of the AC compressor to evacuate/refill it ('83 Spider). I have both an old R12 manifold as well as a converter that screws over the R12 port and allows the connection of an R134 manifold...both...
I can find no information on the location of the low pressure port within the AC system on my 87 Spider. There appear to be three ports, two on the compressor, and one on the dryer. Can someone tell me which is the low pressure charging port?
