Having fitted the final nearside window, I was able to properly install the waistrail beading. I am a bit unhappy with the positioning of it as it rises slightly under the last window. I may try to correct this before painting.
With the beading done I fitted the inner wheelarch cover. This required the manufacture of replacement mounting bracket from angle iron, screwed to the floor alongside the wheel opening. I also had to do some work on the beading around the border of the wheel opening which would otherwise be inaccessible after the wheelarch cover was fitted.
Next, I was able to install the outer wheelarch and mudwing assembly that I had made up previously (see entry for 29/4/2021). I was surprised at how well this fitted. The last couple of days have been spent in finishing the mudwing with filler and preparing the existing half-round wheelarch beading for refitting.
