window felt help

The passenger side front window on my 67 opperation suddenly works terrible.
I took the door panel off and found that the felt thats on the front of the glass was laying in the bottom of the door, the one that slides up in to the front channel buy the vent window. I can't figure out how it reattaches or slides back into the channel. Also I see a small round hole in the front edge of the window glass. Whats it for?
Any one have pictures of how this all goes to gether or a link where I can find info? I asume it would be the same for Barracuda and Dart.
HELP!!!!!!!!!
