I would say very good. The problem would be the cost of shipping.

Put a notice in the 'parts wanted' section. You might also contact a local glass repair shop in your area. They might have a line on cars with a wrecking yard, and then the wrecking yard would do the searching for you.

And I think all US delivery 116 cars came with the defroster. But this is another problem. Is the defroster still working? These can easily be tested, and repaired, before the glass is installed.

Those doing the testing might refer to 'degrees of brilliance' since this seems to be the accepted way of testing a defrost grid. Or they might just talk about Ohms.
