Mystery compressor

I have a Mopar A/C compressor PN: 3846630. The tag says R-12 refrigerant, and complies with regulations for 1962 model year. I don't know the make and model of which this compressor originates. I tried the net, but came up empty. Any issues if I were to use this for my '66 Barracuda? Can I use just any compressor, or do I need to find the exact one for my make and model. If so, do any of you know the part number for a '66 A-body?
