1969 BB 4-speed Barracuda Formula S
I would check inside the dash on the back side of the glove box liner, build sheets were often put there. Also check under the front seats, my 70 Dart bench seat had pieces from one there at one time. Also check behind the interior panels, kick panels, and on the bottom of the package tray, the factory often put them in wired places, I would even look inside the doors under the regulator. Believe it or not but some vehicles even had one on the top side of the gas tank!!!! Would be great to find it, good luck!
