I continued with yesterday’s work today by cutting out a replacement vertical for the corner upright on the RH side of the boot.  I attempted at first to make a cardboard template for this but found this unsatisfactory so made one out of scrap aluminium instead.  The new pillar is about ready for fitting, it just needs a bit of adjustment at the bottom where it meets the boot floor.

During the course of this I found severe rot in the boot floor at the door sill, so this will need to be replaced in due course.
