I'm planning to replace the A/C compressor on my car in the near future, the clutch has been going out of it all year, and it's had a nagging leak for years that has finally gotten bad enough that it won't hold a full charge at all anymore. My first stop is usually Rockauto, and I quickly became very confused, they list 3 different AC Delco compressors for the car and the descriptions are essentially: compressor w/ clutch, H6 compressor w/ clutch, and HR6 compressor w/ clutch. How the heck do I figure out which compressor I actually need? Or all they all interchangeable? Or are they actually the same exact thing just with different part numbers and slightly different descriptions?

So I'm hoping someone out there has encountered this before, or has experience with it and can point me in the right direction. And as long as I'm on the subject, anyone have any experience with any brands other than the OEM AC Delco? I'm inclined to stick with OEM in this case, unless there's a compelling reason to go with another brand. I have used a lot of Four Seasons brand parts in the past, and never had any complaints, but in the last few years I've noticed more and more of their parts are no longer being made here, but in China, so I'm a little leery of buying this expensive of a part if it's now being made in China and would most likely be total and utter garbage.
