I'm not sure if I can give you a walk through or not, but I've done it fairly recently.
The clutch comes assembled with the compressor itself.
What you'll need is a replacement compressor, some PAG oil and a considerable amount of patience.
First, you have to SLOWLY discharge what's left of the freon left in the system.
Pour about 3/4 of the bottle of PAG oil in the replacement compressor and then bolt it in. You're going to want to bolt the lines back up first to prevent the oil from pouring back out as you put the compressor back in.

After you get it all bolted back up (with the belt on and everything) you'll need to leave the wiring harness unplugged from the compressor and tie it up out of the way.
It's really best if you take it to an A/C shop and let them evacuate it, check it for leaks and re-charge it.

I think they charged me around 80 bucks, but to me, it was worth it.

Be careful how much pag you use. You need to measure how much you remove from the old compessor. Add that much back to the new compressor plus 2oz. Too much oil will cause all sorts of problems. You can contaminate the decicant bag in the accumulator/dryer.

Good point.
Yeah, I just briefly touched on the basics to hopefully get the thread going.

ha...this is WAY harder than everyone makes it out to be. My dad & brother had to tear dang near everything out to get to the compressor. There is a bolt that has to be taken out that is almost impossible to get to. I dont know anything about cars so i cant help them. They are in the middle of it right as i type. The manual isnt much help either. Guess ill have to buy t-bones for dinner huh? thanks for your help. I'll tell them about the pag oil.

another question...if there is no pag oil in the compressor when its taken off...then how much do i put in it?

No, well really, there's a bolt that's hard to get out and nearly impossible to get back in.
That's why I said that "patience" is one of the things you'll need.
Get them to stop every once in a while and taken a deep breath and relax their hands and minds... it just takes patience.
