Solved!!! Now the wife can ride in the car! I taped up everything I could think of on the front of the car and took it out for a drive. It looked horrible but fortunately it was early morning. The noise was gone. Ran it up to about 65 mph and it was quiet. I kept taking tape off until it appeared again. Turns out that the square badge bar has a slot in the bottom for mounting the badges and the opening was causing the whistle, The slot is about 1/4 inch wide and as long as the badge bar (about 2 feet). I'll have to figure out some way to cover it up or get a round badge bar. Sure made a wicked noise. Now if I could just figure out some way to modulate this I could have wolf whistle that no one could ever find! Thanks for all of your help. I'll be back I'm sure with something else.
