Shoulder belt issue on 68 Barracuda

Weld a 7/16" NF nut to a large washer as stated above. Then make the hole large enough
for the nut to fit inside leaving the washer flat against the sheet metal then weld the full perimeter
of the washer to the sheet metal.

That would be a good fix, except for the fact the headliner is installed, the carpet, seat belts rear seats ,etc are in the car all ready. Thanks
