Passenger Rear Wing - What Lies Beneath!

Marked out the line to cut along in order to expose as much of the chassis beneath. Then....deep breath...gulp...cut along the line with a 1mm disc on a Dremel.

You can see the previous owner's repair job. Many of these plates/patches aren't properly welded - it definitely can't stay this way. I have the proper panel to weld in but it's a big ol' job for as novice like me! Check the pic below..

Looking upwards into that cavity shows more trouble..this bit will be fiddly because there's good and bad metal in close confines and the panel joins are tricky.. What's more I'll need to do some repair to the 'Longs' first - see the next post for more on that.
