You'll need a belt that is 96.8" with 6 ribs. Dayco makes a such a belt, the part number is 968K6, but this part number should apply to any belt.

You could just use the smog pump delete pulley. Similar to the a/c delete pulley but for the smog pump location. Still available from GM, do a search for the part number.
