Looks great Serge! Just a couple of points:
- the chassis corrodes mostly from water trapped between the body and the chassis on S1s. They corrode from the outside in rather than the inside out.
- it is moderately easy to seal up the front of the chassis but water mainly makes its way to the front of the chassis from the rear! It splashes in through the rear wheel wells and flows down and forward. When you put the chassis back into the body, make sure you carefully seal the chassis to the body at the rear at roughly the line of the seat backs. Fibreglass over a strip of foam to create a barrier to the water flowing further forward and drill a few drain holes in the low points to keep it from building up.
- water also finds its way onto the rear chassis rails through the engine hood vent holes. Again, use carefully placed "dams" to direct this water from flowing further in. You want to direct it down and out your body drain holes.
- finally your carefully sealed chassis will be drilled full of holes when you rivet it back in place. Sealer inside and, more importantly, on the underneath is very important, as well as checking and refreshing it on a regular basis. Inside use a sealer/corrosion inhibitor that stays semi-liquid so it can flow in and around where it needs to. Underneath, use a sealer that hardens but not too much, otherwise it will crack and let moisture through.
