dust cover at the back of the headlamp on Jeffrey Lister's RV8
fell off whilst he was driving home and in a V8BB post he asked
if "anyone has a screw on dust cover/cap access for the
rear of the head lamp casing or know of an alternative solution".
Paul Atkinson responded mentioning an earlier V8BB post he made
December 2020 (which described how he found an alternative cover
on eBay) saying "I have still not been able to find an
original access cap, but nevertheless the rubber item I fitted
remains in place and has proved entirely satisfactory".
