Thanks HR. Well I got these in...not really a big deal- I just needed to slow it down. Here are some suggestions for the next guy doing this. Slide the new channel in just the way it will sit inside the door putting it where the ventilaor arm location is notched out in the door, bottom first. Temporarily put it in place up to where it is notched out on the top of the door. Do not put the clips on yet. Once you've temp put this in place, put your ventilator window & main door glass window in and tighten the screws. Go back to your new channel & adjust accordingly so you can butt it up to the ventilator on the top of the door. Piece of cake...just slow it down on that new paint.
