While what you are asking is feasible it isn't too practical from a business stand point. What kind of guarantee are you looking for on this work? You have diagnosed it and you would like to have a shop adjust your worn out clutch. While it will probably work just fine if it does not or if it quits working in a relatively short time you will find yourself having spent a decent amount of money for a repair that did not hold up. This is why shops do not like using customer's parts or basically holding hands with the customer on repairs, it just makes bad business sense. If you are determined that this is the avenue you want to take I suggest you contact a Volvo specialty shop or an A/C specialty shop and see what kind of answers you get.
