Hi Dave,
The windshield frame to post screws are good ol' 10-24 thread, but good
luck drilling them out. The drill will wander off into the aluminium
sure as you are born...
The toggle clamp stud is 1/4 - 20 UNC. In some desperate cases you can
get away with drilling a set of holes right next to the originals and
moving the windshield up or down the post 3/16". May not be the ideal
solution but you can at least save the post.

Subject: Windshield Pillar Screw Threads
All,
In my windshield pillars, I have several of the little screws (that hold
the
windshield frame to the pillar) sheared off in the pillar. I will need
to
drill these out and run a tap thru them. Can anyone tell me the correct
thread size for these screws. Also, the "toggle clamp retaining stud",
as
Moss calls it, has likewise been sheared off on one of the pillars. I
need
the thread size for that also. This BSF and BS Whitworth stuff has me
largely
confused. I'm climbing the learning curve, but it's slow going. Thanks
in
advance.
Dave
