well, first , i assume you mean the connector in the red circles...
your compressor part number appears to be 89019337 , and i see it listed about $375 the lowest avg price. the part number 3 in the blowup is NOT listed anywhere i can find in GM parts manuals. since they show it as a single item, it can be bought (somewhere???????????) i sure cant find it.
sold as items 3 thru 8 as clutch.... (not item 3 by itself that i can find) , gm # 88958094 , acdelco 154955 , about $130 lowest avg price

Reason: found the part #
Not sure how easy it is to do while comp. Is in the car?
Has anyone done this?
I've done it.
I unbolted the compressor and pulled it forward/up while leaving the refrigerant connection connected. It will barely squeeze through enough so you can point the front of the compressor "up" to get to the snap rings.
There are a few snap rings that hold the clutch on which are a pain to get off.. it becomes much easier if you can get good access to the front of the compressor.
I used an AC Delco version of the clutch and it has worked fine now for 6-8 months
I have a 2009 Vette and tried for 2 days to get the clutch off with no luck. Just too dang tight in there to get the spanner wrench on the clutch to hold it while trying to back out the screws. I had thought about removing the compressor but didn't want to have to drain the refrigerant. Sounds like you found a way to make it work. Did you have to completely remove 4 bolts to move the compressor? I talked to a shop and they said the "book" says they have to remove the front end....and then re-align the car after putting it back on.....all to the tune of $650 or so.
Yeah I removed the bolts to the compressor and with a big of tugging was able to pull the compressor up which gave much easier access to the clutch. In hindsight I wish I had just replaced it while I was at it but I didn't
It's possible I had to loosen the front cradle bolts to give me a little more room to get to the bolts, I'm not 100% sure. I am 100% sure I didn't have to take the front end apart, I did it in the driveway in an afternoon.

iI removed the broken compressor clutch from the AC compressor and found that the inner bearing race had spun on the fit on the front of the compressor. However the clutch bearing spins freely and smoothly.I was hoping to replace only the clutch but the compressor nose is scoured by the bearing race spinning on it. I could use gap-filling bushing adhesive- it may work, maybe. Anyone else have the same dilemma? Hoping to avoid replacing the compressor and whatever else needs to be replaced. Getting the clutch off of the compressor was easy compared to getting the A/C compressor out. Just needed to remove the bolts holding the compressor in place to re-orient it slightly, and get the right snap ring pliers. I realize that the compressor may be the root cause of the clutch failure but I do not see the reason for the bearing race to spin . One of the 3 spring arms had disconnected on the clutch disc..

Why do you wish that you had replaced the AC compressor? Did it fail soon after you put a new clutch onto it?
I am debating whether to replace only the clutch but the bearing fit on the compressor is compromised.
Clutch only is much easier than trying to get the compressor out.
I didn't have to remove anything to get the AC comp. clutch off- except the bolts holding the compressor to the motor and a radiator hose that was preventing access to the pulley snap ring.
Because it’s not much more work to just replace it and mine is rattling now. I spent $100 on a clutch and did the pita install (mine has a supercharger so I had to remove that and work around some of the piping). Could have spent another $150 and replaced it with a new one and been done

I guess here is the proof.

Ouch. I'm sorry to hear that schpenxel.. I just seconds ago commented on another thread this guy posted in explaining this identical condition unfortunately being a common occurrence.
