Hi Guys
Thought I would add a few ideas about searching for parts. Although a lot of yards are picked over it seems some parts are forgotten such as electric wiper motors they can be on the most basic cars, power seats day/night mirrors a/c brackets ect. Some times it seems if you look the car over hard enough something remains. Also when looking to add power windows some parts will interchange from other Ford products such as window motors some switches ect. One part that seems to be hard to find is the rear power window regulator I do not know for sure but I have been told that a 1958 Lincoln convertible rear window regulator is the same although this is a rare car you might see one in a yard and I think it would be worth a look maybe someone knows if these fit? I am adding a link to yard in Minnesota They can be emailed for requests. First time I was there was 1974 they had 1000s of cars I went years after that and found it somewhat picked over, but they still are adding vintage cars to the yard.They may have a bracket or small part you are looking for?
