I watch 3 hours of video that I made of my car restoration. Wow! I learned alot. I took video of every bolt, shim screw, missing screws how the bolts were oriented etc... This was back in 2000 when I was taking the car apart.
From what I have seen thus far I did have this part in the front header bow.
I have two more videos to watch and I hope that maybe I covered the painting I did of the frame.
At least I know now I had the part. I typicly don't throw anything away. The question is where the heck is it?
