Still no pictures, sorry. But I did reinforce the other side on my car while I had the interior panel off for some cosmetic repair.

I again wrapped a piece of coat-hanger wire (approximate diameter 3/32") around the plastic piece that always breaks. I did not make any grooves in the plastic to retain the wire, which rests nicely between the operating cables and the metal of the regulator frame. It took me about fifteen minutes to bend the wire to the right shape and secure it to the regulator, without removing the regulator from the door.

It's important that the wire be quite snug if it is to help. If there's any flex in the plastic, it will eventually fail. If either of mine do fail in the near future, you'll hear about it here.
