The rear arch of the XJ-S was looking quite scabby, so I decided to see how bad it was.  After a bit of cutting I was left with what is shown in the photo below.

Some folding of metal and welding returned the arch to a solid condition.  I recreated the original seams to try to keep the arch looking as original as possible.  A little more work was needed to finish the job, but I didn’t get round to taking any more photos.
