01 AC compressor part number?

[Marlin]

I need to figure this out. If I order one from Isuzu will the compressor come with the Clutch already on there?

My A/C is now only coming on after I get the engine warm, weird huh? Is the fan somehow getting stuck/going out?

For 800 bucks, I would think it comes complete, but when I tried before, they had the same part number listed for the 01 as the 99. Which I know is incorrect.
