379 Peterbilt floor full of holes and falling apart? Airbag Mafia has engineered a 1 piece replacement floor for your fresh 379 build or restoration. An original Peterbilt floor was blue light laser scanned and CAD modeled to insure perfect fit. The floor is laser cut out of .125 aluminum and and CNC bent to match the original component. We have opted to make this a one piece design to reduce areas of future corrosion and have a smoother over all look.
