The first step is to take lots of pictures before taking anything apart. It will seem like way too many shots, but undoubtedly we will be missing some view we need as re-assembly takes place.
Next, the disassembly begins. All accessories, the bumper, hood, doors, and trim panels go first. A real tribute to Mack is the fact that very few bolts are rusted too badly to be backed out, and only the running boards, tailboard and some fender sections have any holes rusted through.
