There is a special Tenax stud that was originally used only on aluminum frames.
It doesn't thread into the frame at all, instead it passes all the way through
and has a slotted flathead "nut" that comes in from the other side. Only
noticeable if you look for it, and not objectionable then, IMO. I haven't
tried it yet, but I am planning to use one of them to 'repair' a stripped hole
in my original windshield frame.
TRF had the studs reproduced. I don't recall the PN offhand, but it's in the
SPC. When you go to drill the frame, use a fine stone to remove the rake at
the tip of the drill (basically dull it a bit) so it doesn't dig into the soft
brass under the chrome. It might be wise to use a Dremel and a small abrasive
burr to cut through the chrome layer, to avoid the possibility of peeling it
off around the hole.
I will also be using a stop collar on the drill bit, to limit depth and
hopefully keep it from hitting the glass, but I assume you won't have that
problem.
