Karen,
If you buy one of the inexpensive R-134 installation kits, they come
with adapters for older R-12 systems (like your GMC has). Once you
screw on the correct adapter, and only one fits, you will only be able
to hook up the gauge to the correct side of the system for filling and
monitoring the pressure on the low side. It's foolproof (sailor proof
too).
