1990 Chevy Lumina 6 cyl Two Wheel Drive Automatic

My ac clutch has seized so i've got the serpentine belt and the bypass pulley. I just need to know how to mount the pulley and run the belt. A diagram would be helpful as well.

Im not sure if you can just remove ac compressor and install a belt, im almost positive you need to install a bypass pulley in place of the ac compressor and it uses the same belt. They sell ac bypass pulley kits, I just installed one on a lumina, I bought it at advanced auto parts and I think it cost about 35 dollars
