No, not a "grid" problem as I see it. The problem I posted was that the
spade lug connector which is (i.e., was) soldered to the righthand side of
the window grid (and provides the grounding of the grid) has broken off. It
needs to be resoldered (or otherwise affixed) to the two small, rectangular
patches of metal substrate from which it broke away.

In my case, nothing needs to be "bridged". Just need an adequately
conductive and mechanically strong connection made to the metal areas that
already are well-bonded to the glass (and to the grid). These contact areas
are rectangular--about 3/16 X 1/4"

I'll try to find out about these. Maybe they'll eliminate the need to
resolder the connector.
