Can jamb vents be cut into a 1968 gmc?
 

Has anyone added jamb vents on a 1967 - 1970 cab? It sounds like a hurricane when I open the cowl vents on my truck at freeway speeds. I suspect the vents were added to make closing the doors easier with the windows closed, but anything to quiet the whistling would be great. New weather striping did not help.
Thanks

I don't see any reason why the can't be added.

Here's a Link to a recent thread on the noise issue.
