That's a quick fix. Just make you one out of sheet metal. Bend it into an arc, so to speak, then add some bead rolled lines in it for strength. Voila!! There you have it. That's what a buddy of mine did some years ago, but he no longer owns the car anymore. Otherwise, I would get you some pics. You're gonna have to make your own since there isn't anything out there on the market. Either that or switch to an electric fan.
