I made a solution that needs some refinement but the premise worked well.
I made this not to cut the whistle but to get my truck inspected and receive plates. I bought the truck with shaved mirrors which would not pass inspection to receive plates.
These are RAM product motor cycle mirrors. Keeps the cops off my back without bolting something permanent until I find what I want.
The Ram ball is threaded and goes through the hole in the glass. Made a spacer the glass thickness and used rubber washers between the spacer and stainless steel washers.
Inside is a piece of aluminum tubing that has round edges. Inside has the same washers and a lock nut.
You can then adjust the tightness with the lock nut until the whistling stops.
Instead of the RAM ball use a chrome carriage head bolt and adjust the washers and spacer accordingly.
I liked it because I can also mount a Go Pro if I want.
This was thrown together quickly. I was thinking I could CNC a nice handle that looks better.
My seals are shot and cranking them down sealed them completely.
