Ok, just want to make sure I am on the right track. Is the low side service port on the back side of the compressor with the red screw cap?

Ok it looks like I answered my own question. The port on the front seems to be the only port that will fit my adapter.

I ran a couple of bottles of stop leak through it and some refrigerant. My next question is what PSI do I charge it to? Do I read the gauge with the engine and compressor running or just a static pressure?
Now that it's charged its reading 80 psi at static and 50 psi while running. Now my AC belt squeals when the AC compressor is running. Seems like a sign that it might be over charged. Anyone have some insights or advice?

Typical low-side pressure should be 25-30 psi with the compressor engaged.

Backed it off to 28 PSI and tightened the belt. Cold Air! Woohoo!
And the new owner surely appreciates itGood news indeed.
I had to replace my compressor and clutch.
Probably owe you a few more of these
