Wow, a lot to take in there. I know that I have read this before but it always fascinates.
In response to the original post I still prefer to keep my rod adjustable central mirror. Unlike a van or lorry, the side mirrors on a Morgan are low in relation to eye level and even when large and convex there is still a bit of a blind spot dead centre and close up behind the car within which a bike can sit if at traffic lights for instance.
I agree about the hood quarter lights. Mine doesn't have them and thats one of the reasons why it hardly ever gets put up.
