Essentially they're all the same - Compressor is the Nippondenso Model 10PA20C. The LT motors (92 up) have a different manifold (it faces forward) and probably uses sealing washers for the main hose instead of o-rings. I know there are different clutch #'s but they all use the same diameter coils and 2 pin connectors. My guess is that some may have the diode in the coil, the others are in the connectors. The diode keeps it from frying parts when the clutch disengages.

Hi Dan!!!Just spent the weekend sledding!!When the sledding is done I need a new ac compressor and I see the 1990 is cheaper and I was just curious if there was a physical difference or just the seals for different freon.When I change it out we will be up for a little golf and beer!!!
