Is the large black nut on the refrigerant line coming into the accumulator a cover for a nut underneath, or this part of the hose or something? Is it metal, plastic or composite or something??? 
it is quite different from the other connection.

The images with the information for your link seem to no longer be there. Do you still have them? I cleared the cache on my browser and now I'm stuck.[This message has been edited by computer_engineer (edited 07-19-2018).]

Looks like the image server is down, give it a few hours.

the material, is it made out of steel or aluminum? The reason I ask, is I want to make sure I take proper care loosening the refrigerant connectors so I don't strip them. Something tells me that finding replacement lines may prove difficult. 
|

Those are all aluminum. It doesn't take much torque, because the o-rings do the actual sealing. Finding the lines that run under the car is a PITA, I had to drive 4 hours down state and another 4 hours back with a new set (originals were cracked below the front compartment)

It's not a cover, it IS the nut, that one is plastic. Some are metal on later cars.

What is the canister shaped item on the compressor hose? When I go to blow that hose out, do I have to be careful with that side? Is there anything inside that canister? [This message has been edited by computer_engineer (edited 07-20-2018).]

It's a muffler! What's inside?

On my compressor, which I think is a HR6 (it's on a late 87 GT 5 speed), I have a white collar switch and a red collared one. You told me the red one was the high pressure switch, is the white one a low pressure switch. The web page with all the part numbers lists this as the "Fan Switch". Are they the same thing?

Yes, the white mushroom switch kicks on the radiator fan at a lower pressure. The fan should run anytime the AC is on anyway. It uses the same fan switch connector as the radiator fan switch on the V6 cars. The switch will close at ~280psi
