Chrysler used the C171 compressor as standard issue with factory air conditioning systems in 1987. To remove the AC clutch (which can be done with the system charged with refrigerant) you have to remove a 13 mm nut on the compressor shaft and then use snap ring pliers to remove an internal snap ring. There are threads on the inside surface of the exterior clutch plate that mate with a special puller and allow the clutch plate to be removed. You could check an auto parts store and its loaner tools and maybe find the special puller. Don't attempt to use a hammer or screw drivers as a pry removing tool. Once the exterior clutch plate is removed there is another snap ring that holds the clutch electromagnetic coil to the AC compressor body.
