Well, with nothing to lose at this point by trying, I tried to fit the back window in---- too small. How the heck you can screw up when you have a reprint of an official Ford document giving the measurements is beyond me, so that one's gonna have to be replaced. The door windows are TIGHT, but I was able to get both felt channels in, so I imagine they will loosen up a little with time. I haven't tried to actually roll the windows up and down by using the regulators yet, as the silicone bedding material hasn't completely dried yet. But at least all the stuff fit into the door this time, so I am making progress....
