The M-110 engines used an R-210. I'm sure this would work, but may not take as much refrigerant as the system originally called for. Remember, all of the nomenclature means something. In "R-210", the "R" means that the compressor has suction on the right side, the "2" means it's a 2 cylinder, and the "10" means it's displacement is 10 cubic inches. The biggest thing to make sure of is that the suction and discharge ports are on the correct side.
This particular compressor has flange type fittings on top in which a hose connects sideways to. The m-110 compressors have O-ring type fittings in which the A/C lines connect from the top. Obviously, fitment of the lines will not be what it's supposed to be, and not possible unless additional 90 degree fittings are found.
