yes, sorry about the confusion. The division bar seal (rivetted) was fine, it was the triangular weatherstripping that goes around the frame of the vent window. It was way too thin and didn't provide enough seal. there was about 1/8 inch gap all around. The old ones were actually in better shape!
Got it all sorted out. I guess I should post pictures but every dang time i walk into the garage, I get to work and forget about the pictures!
