Yes, like so many areas on this car it could so easily be enough to make you think it's not worth the effort!
But still I keep going...

As the rear inner arches look likely to be extremely tricky if not downright uncomfortable to repair with the car sat upright and plans to put it on my rollover jig then the repairs to said area will be left until I can get the car upside-down.
Trouble is the jig mounts through the bumper mounting holes and seeing as the outer arches need repairing I need to be able to mount the bumper to get the alignment right.
As you can see in the picture it has at some point had some repair sections grafted onto the outers, they didn't look too bad but I spied the rivets from underneath and the alignment to the door wasn't quite at the right level.
