Hi Andrew
your old headlight with the loose reflector, all thats up with it, is broken adjusters
there available on ebay, in a better resin that will last and won't break again, there quite easy to replace and don't take that long
your headlights will eventually go loose and these adjuster will break because they go so brittle and break
I did mine and it's something I can forget about now, have a look on youtube, there's video's on how to do
cheers
Joe
