Anyone else have a car with G01 Electric rear defog?

More details on the Swiss mopars are here:

High quality Swiss made A - Bodies

In 1973 they didn't produce any more cars in Switzerland, AMAG then only imported cars. The imported cars got H4 headlights and the special turn signal lever for the mandatory headlight flasher.
But I have never heard from a conversion to a rear window defroster after 1972.
Very interesting - can we have more information to Your car?
