Whilst chasing down all the rust I have cut more out of the floor, much of which was done from under the car 😟
Good news is that the rust did not spread further back, so I can make a up a piece or 3 to replace the rotten bits and then I can start treating the rust in the chassis rails, after cleaning them of course!
Many of the pictures show the hole after being cut, it was a bear of a job so I did not pause to show progress.
