Slow progress, I was away all of December so have only just started back on it. I'm working my way down the drivers side inner shell. I've cut out and replaced one of the rusted inner sections. Now means the outer section I made has a good base to be attached to.
I've been trying to work out how best to finish the rest of the replacement pieces to the inner roof shell. When I took the outer wheel tub off, I released that whoever replace it just tacked it to the over the top of everything else. When I unpicked it, I discovered that the old outer tub flange was still rusting away in the sandwich of metal. So now that it's all out, I'll have to re-assemble the inner and outer tubs, then add the patch pieces to the lower part of the sail panel as it is tacked to the outside of the tub flanges. Hopefully that makes sense ...
In order to do the outer wheel tub though, I had to first repair the rusted out section of the rocker ... Still need to clean the welds up on the rocker repair and cut the drain holes back into the bottom. Reasonably happy with how it came out. The 1.6mm sheet was a lot more challenging to shape than the normal panel thickness.
The last pic is the rear section that I need to replace as well. I'm thinking I'll continue that patch all the way through to link up to the piece I've already replaced. It's totally rusted out and pitted under the vertical roof support. But I need to take out the parcel shelf corner to do that first ...
