Based on the extent of the rust around the area on the floor which the sills attach to and a lot of the perimeter sections I decided the best approach would be to replace the floor entirely (this will give me a chance to clean up most of the underside properly and restore it fully).

Starting to chop the floor out in sections:

Front half out:

Nearly there:

All that I could find of the offside middle sill:

And majority of the floor out, just the areas around the edges left to unpick from the walls (just to think 4 months ago I was driving this around as my only vehicle!):

Having assessed the cross floor supports it looks like I’ll need to do the following:

  • 1st support – Already taken out, new one to fit.
  • 2nd and 3rd I beam supports – In fairly good nick so I’ll repair the sections that need repairing.
  • 4th tophat – Minor repairs.
  • 5th and 6th tophat – Given that these are only welded to the chassis legs now and need some significant repair I think I’ll just replace both of them to save time.
