Belt line catwhisker removal

Looks like you had the door panel off anyway so... There's a eccentric travel stop on the window regulator. Loosen the lock nut and rotate the eccentric with flat blade screw driver so window winds further down into door. Inner and outer whiskers peel right out, drop right in, once the glass is out of the way.

I was looking at the quarter window felts to install and noticed the curve doesn't match the felts. Do you have to bend them to fit? You would think they would be manufactured correct.
