Toyota Repair: 1993 2.2 a/c compressor, remanufactured compressors, diea

Question
Mine is rattling I was told the clutch in the a/c is bad.
Where is the part number on mine ?I would think it is the factory one still in it only 177K on it.
Better to replace the whole thing right?Rather than just the clutch?

Answer
Most of the time when the clutch goes bad it tends to damage the front of the compressor housing as well so it's a good diea to just replace the whole thing especially at this mileage, toyota has remanufactured compressors available,part number is not needed just tell the parts department what year and model mit is and the vin number.
