The firewall had an opening for the stock heater box, but we planned on converting this car to a Vintage Air system for integrated heat and air conditioning.
Adam trimmed the opening, then brewed up a close-out panel with the Mittler Brothers bead roller that added a little style to the firewall.
The original panel was cut on the bottom, and the upper seam was drilled and separated at the original spot weld locations.
The new panel is TIG welded in place, and the butt-welded seams are metal finished smooth.
The panel is metal finished on the inside of the car as well.
