Thanks Harold. You don't seem to have the lower black valence in place in your photos??? Seems you are using the flexible filler panels both at bottom and sides of the cavity in front of rad. See the pics in the post prior to your reply. Very confusing.
Some of the pics I have the lower baffle and a couple I don't. I Only have flexible fillers on sides not at bottom.
In this picture in the service manual, lower right shows the seals Jim and I have in place.
The metal you see in your picture in the bumper support bracket. These seals attaches to it and the radiator core so there is no open gap in in the corner you see. So all all goes through the radiator instead of forced through the open gaps.
