hydraulics

i have a 92 k1500, i want to put a hydraulic pump onto the motor, some snow plow truck and tow trucks have this hydraulic pumps on the front of their motors, i guess the best way to explain where it is located would be, to tell you it's something like an A/C compresser, as you can see i REALLY need help on this. i want to hook up a hydraulic pump so i can run a plow and a towing unit on the back. thanks


ok after some looking about and talking, i have found out that it's a hydraulic clutch pump that im looking for, so would any one have info on the pump and where i can get a use one to put on my truck.
