The box under the dash replaced the ash tray and stock heater controls. Switches for fuel pump, electric fan, ect. will go there. I have more hours in the body then I would like to add up. Both side floor replacement, both full quarter replacement, filled firewall and shock towers, blended rear valence and rockers to quarter panel, rear extensions blended in for Shelby style deck lid, filled grille opening in cowl. Thanks for the great comments.
