Fred, the door glass probably shattered because it had scratches on the glass
surface. These become stress risers on the tempered glass. The scratches
typically are vertical ones caused by the two (non-original) attachment screws
for the interior door-pull handle being too long and contacting the glass when
it is rolled up and down.
The original door-pull sheet metal screws can pull out of the inner door sheet
metal over time or instantly when pulled too hard when closing or slamming the
door, causing an enlargement of the holes. It then becomes a problem finding
new sheet-metal screws that are large enough in diameter to screw securely into
the holes, while also short enough not to contact the glass. Both of my door
glasses had such scratches when I bought the car, and the driver's door
shattered suddenly. Not recognizing the real problem, I replaced the glass
without replacing the screws, and the same scratches and same shattering
occurred again later.
My permanent fix was to weld some square machine-screw nuts into the screw
holes (this required filing the holes into squares to fit the nuts, making sure
the holes stayed centered). I cut down the length of the matching screws to
ensure they wouldn't touch the glass. The machine screws and nuts have a
stronger tensile capability than the sheet metal screws and inner door panel
and after 10 years no problem with scratches or the door-pull handle pulling
out.
I bought new door glasses from Moss Motors and they work fine, but the sealing
rubber also supplied by Moss didn't work at all. This was 10 years ago, so
they may have fixed that problem since then. I had a local glass shop install
the glass into the frames, with new nylon guides.

Subject: [Healeys] Window glass
Listers,
I closed the door on my 66 BJ8 a couple of hours ago and my door glass
shattered. The window was down so only a few fragments hit me. I will have to
remove the door panel to gain access to the innards. Anything there to look
out for?
What are recommended sources for replacement glass that fits properly?
Thanks for any and all help!
Fred
