Still motivated by success with the inner wings I started on the driver's floor pan and sill. The first thing was to remove the flat sheet of steel which had been welded over the original floor pan. This proved easier than expected owing to rough welding and for some reason ease of cutting the sheet with an angle grinder. Underneath it was not good news.

Unfortunately the original floor was totally rotten. So I spent the rest of the day carefully removing it. And this is what I finished up with. As you can see the chassis rails are exposed and mint - the same as the other side. Nice.

I also made up a new panel using a new floor pan and part of a new inner sill to drop into the hole I have created.
