You would need to get a fan shroud, a clutch fan to match the size of the shroud and the rotation of the water pump, which is likely NOT the same as the ones that came on any Camaro with a clutch fan. I know that Chevy trucks from the late 90's have a fan that fits the bill, but you'll need to do some measuring to figure out if the shroud and fan protrusion will match up.
Alternatively, if you can follow instructions well, pick up an electric fan control kit (get one with an in manifold sensor, the push through radiator kind tend to break off.) and hook it up with the main power to fans wire on the red from the old fan relay, the temp sensor lead on the brown wire from same, and the green AC wire spliced to the green wire on the AC clutch. Took me about 45 minutes to do the whole thing on mine, including putting on two fans and lengthening my wires for a cleaner look.
Edit: You can even do this and keep the stock fan hooked up with the new controller, just use a single solderless splice clip on the hot fan wire, I believe the ground wire is already correct.

Could also work. I'm admittedly not up on clutch fans. I personally hate the things, power robbers that they are, but if it's designed to work with the counterclockwise fan of the serpentine system, it should work so long as it fits the shroud you get.
