the foam was in remarkable good condition. I took a closer look and found this

 

Mission accomplished. I used the old wire that had the thread bare covering on it (now I know that is the remains of the orig flap) removed the seat cover, put that wire in the flap, reinstalled the seat cover and used another wire to hook it and pull up to the center. After hog ringing that center in I put a few more in by just grabbing the flap (easier now with the center pulled up)  and hog ringing in two more on each side. The effect is more subtle than I thought it was going to be based on how tight that pull was, but it does look better. Thanks gang for steering me in the right direction here.

Excellent. See? You had the power all along!

he head liner is a bit droopy and it was rubbing the top of my head. So before I do the passenger side seat I will have to get to work on re attaching the head liner. I am getting better at getting that seat apart.
