I believe it's behind the wheel well cover on the passenger side just behind the front wheel. You'll need a T-30 torx and a Phillips head to remove the panel. The port sticks out of the side of a silver tube.

That sounds like the expansion valve.
I highly recommend taking it to a service station because you will need to have it retrofitted and the freon changed to r134a instead of r12 ---- DO NOT ADD r134a to r12 it will lock up your compressor ---- But the low pressure valve is the one closest to the firewall it will look like a tire valve stem. The high pressure is located closer to the ground.
