The outer arch is on too. Needs tidying up at the bottom corner though. Unfortunately a big gap remained since it was difficult to trace out (the arch was a bit twisted, could only fit it by cutting off the end of it as that part didn't line up with the panel), lined up fine everywhere else. One big problem i have with them is that there's a big gap between the outer edges of the arches (where they otherwise would be spot welded). They are both fine in their positions but don't match up together.... will be rectified with filler i guess. It'll look good and will also be very rigid. Time to go on to the front arch tomorrow...
