Hi,
Thank you for the answer.
Concerning the car shown above, impossible to check on it. I don't know the owner.
But for my mustang (same model), built the September 25th, 1964, you right !
There's an additionnal bracket welded on the firewall to adjust the export brace.
However, there's no link installed Under the Dashboard, between the
brake pedal support and the bottom of the dash.
