I started cutting the floor out on Saturday. I haven't got very far now because I keep finding more rust and holes.
This is where the floor meets the bulkhead at the front. There should only be one layer here.

From underneath, looking to the front right A pillar. I'm trying to work out how to remove the rust to be able to weld some new panels on.

Across the inside floor there is a cross-beam. This is how it looks from the outside.

I may have to buy some sheet metal to patch up the bits I don't have panels for.
