Review on 🚚 Truck-Lite 97662 Rectangular Stainless Steel Mirror, Medium Duty Truck, 7-1/2''x10-1/2'', 5'' Elbow by Robert Tyus

Received these mirrors to replace the stock ones on my 1984 E350 van. They are good looking and well built. Installation was very easy, all you had to do was slightly drill a hole on the standard bracket. Was very satisfied with the first ride, then the whistle went off! These things whistle something angry, and it's a very annoying whistle. Also note that if you put one of these on the driver's side, the mirror will loosen and unscrew after you've closed the door a few times, which is very annoying. I sprayed some Lock Tight onto the thread hoping that would fix the problem. But I don't know what to do with the whistle.
