I second the thought that there should be no stress at all on the panels.
Not that I have an Ulster.
Also, on my special, I have a thin rubber washer wherever possible on each side of the panel.
It helps with absorbing the flexing, it stops (slows down) the panel being fretted through, and helps slow electrolytic action.
I didn't think to use a washer between sidelights and mudguard (fender).
When I finally removed the sidelights, the small steel cones between light body and mudguard were full of corrosion products, and there were neat holes the size of the cone bases eaten through the 'guards.
The result of 20 years or so of electrolytic action.
