Front Floor Pans Before and after shots.
Back
My best friend Brent did an excellent job butt welding in new floorpans & firewall extensions to replace the original rusted out ones. The cowl was not rusted out but the air conditioning emptied out onto the floors and the windshield had a crack in it for years. This is what caused the rust. I sealed the seams with windshield urethane.
Here you can see my subframe coming into the rear floor pan.
