The cab on my 53 AD one ton has rust in these places, two inches up on the toe board, from the toe board back to the seat riser, and half way up the side kick panels. The cowl outer panels are perfect (the fenders bolt to this part).Is it possible to remove the floor,toe board, and kick panels without disturbing the cowl panels? Would I be able to drill out the spot welds etc ? Thanks --- I'll be on line for a while, if you need more info!
