Who will be doing the R134 charge? You or a shop? The shop should have a high pressure charge system that will use the port near the drier. You should not attempt this with a can of R134 from a parts house, can be quite dangerous.

The R134 cheapie conversion kits from a parts house or Pep boys or Wal-Mart will have a device that converts the low pressure port on an R12 compressure port into on that will accept the quick-disconnect R134 charge hose.

Perhaps that device is available without getting the whole kit.

Using the low side port allows the can pressure and the compressure to get the R134 into the system quite easily.

If there is a problem with having the compressor kick in, there is a way to jump the low pressure kick-out switch.

Good Luck,

Bob

PS: I, too, am facing this conversion - but haven't yet done one. The above may be corrected by someone who HAS done one.
