Kerry; I wonder if there is a way to rebuild the hydraulic cylinders used in those early power window mechanisms? If you look at the ones used in other applications there is usually a way to take them apart to replace seals, pistons and the like. One interesting question was how the company fitted the mechanisms in the front doors in the first place if you had to cut the sheet metal to remove them. It may be a little non Imperial but a friend of mine had to work on a 1940's Lincoln, when he was a young mechanic. He told me that the rubber lines would keep coming off around the hinge side of the door jamb leaking fluid all over the carpets. I don't know whether the Imperial would have the same problem as it likely had a better design then the FoMoCo system.
