Continuing the rust removal in the rear left hand floor pan area.
I've cut through the floor pan to show the several plates that have been applied over the years
The captive nuts for the subframe stiffeners have been removed...
...and I've bent the metal where they were fitted down and out of the way so I can make a new replacement part to the "step" panel behind.
I still need to know where those stiffeners go so I haven't cut off that bit of metal just yet!
The plan is - as ever - to repair the individual panels to keep the structure as Mercedes intended.
