Need help with a/c compressor

[coolioni]

I have an 83 720 4x4 . I need to replace my compressor. the problem I have is that I ordered one from a used part store online, and the compressor is not the same that is in my truck right now.

The one in my truck has the connection to charge the system right on the compressor, but the one they sent me does not have the connection on the compressor.

Does anyone know if they made different compressors for an 83 720 pickup ? Or do you think I may have a differnt compressor on the truck ?

Thanks!

Don't know about your model directly but I suspect that the difference is between factory installed and dealer or aftermarket installation. It's like Mitsubishi vs York.
