The metal bracket that holds the front weatherstrip seal in place was rusted in spots and needed some repair. Then after I got it installed, I found it sealed OK at the 2 corners but did not seal tightly against the trim all the way across. Not sure if the header on the top was warped or what was wrong. Solved the issue by gluing a narrow strip of weatherstrip across the top front edge of the seal. And seems to fit OK now.
