The other rear arch is done. The combination of humidity, sweat, modena green paint and the grinder meant I had a bit of the incredible hulk look happening. It's also cheaper than paying to have a sauna.
Anyway, process was the same as the other side. Start by aligning the two lower edges then the top then use self tappers to fit the entire arch. Reform the lip with the panel beating hammer, remove the arch and give it a coat of etch along with the quarter. Then apply sikaflex and rivet it on.


This is a good view of the self tappers.

Give the quarter a coat of etch around where the arch rivets on.

And this is the final look.


Last thing to be done on each is welding the rods on to the bottom of the sills.
