shims behind the nut or the clutch? I don't have a clutch puller tool. And I just did a quick search and I don't think Advance sells shims for A/C compressors.

Once you remove the nut, the clutch comes off without a puller.
In your situation, you would need to remove shims, not add them.

Okay, so is the air gap the lip between the clutch and pulley? or somewhere else? And is it .017 inches or mm?

Well the feeler gauge shows the air gap at .021"
But none of my sockets get to that nut in there, how do you get to it?

You need a deep 6 point socket that is thin walled.

Chrome sockets are thin sockets.
I believe it is either a 14 or 15 mm nut.

Okay, nuts. That is one that is pressed on. It does not show it in my data.
There is a puller that screws into the clutch and pushes it off.

Okay, so got the clutch plate off with the tool. No spacers here. Pulley is held on with a snap ring I think.

So the scratching is definitely gone. But the compressor seems to go on/off at 2000 rpm. Is it supposed to do that? Can kind of feel it while driving, and doesn't affect the temperature

Compressor turns on and off when over 2000 rpm. Can kind of feel it while driving. But no scratching like before. Low side 25 psi and high side 250

Low side is low. At 2k does the low side drop off more.

Yes. The low pressure switch shuts down the system when the low pressure hits 20 lbs.
That indicates a bad expansion valve.

can't be. The orifice tube and condenser are maybe a month old. I probably just measured it wrong.

The gauge is accurate.
Yes, it can be. If the tube is defective or clogged, it will do this.
Take the readings again and post a picture of the gauges at 2k.
