It took ages, nothing was straight forward ( or symmetrical for that matter) even the escutcheons took hours to modify but its done.
I then moved onto my mirror centre stay from Brasscraft. I had tried to fit it years ago but it was never going to mate up with the screen so I had given it up as a lost cause. Upon revisiting the problem I decided it didn't need to bolt to the bottom of the screen, just the body. After much filing and grinding it fitted.
Its not finished yet and still isn't as tidy as I would like but its is definitely getting there.
It definitely feels like I am getting nearer to that paint job.
