Default 1992 Expo air conditioning low pressure port location

Hello,
I'm trying to recharge the air conditioning in my 92 Expo SP AWD but can't seem to locate the low pressure port. I have the manuals for the car but they don't show it either. The book shows the high pressure port next to the drier in the small metal tube (very accessable), and the over pressure release port right on the compressor itself, but no where to add the refrigerant. Also, if you know about freon, I've heard there is no problem mixing R12 and R134. Is that true?
Thanks, Mark.

should be on the compressor.
and NEVER, EVER mix the two refridgerants. If you dont have that basic knowledge, you should NOT be working on your AC system.

Article that discusses mixing refridgerants, albeit pretty old. http://yarchive.net/ac/oils.html
