Anybody got a clue as to where the factory got theirs ?

One of the glass clamps separated from the cable(or whatever) so it cocks in the tracks.

I suspect Fiat, but have not been able to find any pics that correlate to mine.

I found an old parts pricelist that shows a "discounted" price of well over $600. I'll go the Kitcar route and use a Ford Ganada lift before I spend that kind of money for that.

Thanks.
