I have two questions regarding installation of rear door glass in a 1937 Fordor: 1. What is the correct order of assembly, particularly regarding window channels and glass. I installed the window channels first but could not get the glass in. I removed the window channels, installed the glass and then the channels and got it together. Was I just not holding my mouth right or does the glass have to go in before the channels? 2. Without the regulator installed the glass does not move freely in the channels particularly as it nears the top of its' travel. Something is out of alignement! Any tips on locating and correcting the problem?

The glass goes into the channel when the channel is out of the car. Otherwise, is is very difficult to firmly seat the glass. If the glass binds when in place, it is likely that the glass may be too thick for the application, if it was not from a specialty supplier. A very small difference can cause the problem. Be sure that the regulator is in good condition, without any worn teeth that allow the glass to cock as it moves. A bit of white grease lube on the moving parts helps, as does a bit of silicone spray in the glass channels. Replacing door glass always seems to be a challenge, due to limited room, and the often razor shape edges of the openings in the door.

Thanks for the response Bob. I believe I should clarify my terminology for the rear window components and it may be I'm calling them by the wrong name. What I'm calling the window channel is the U shaped, flexible piece with cat whiskers on both sides of the U, fixed to the door frame, that the glass slides in. What I call the glass channel is the metal channel attached to the bottom of the glass with bedding tape that engages the window regulator. After receiving your response I checked the glass thickness and opening in the window channel with dial calipers. The glass thickness is 0.23 in. and the opening in the window channel is 0.32 in. which should be OK. I did confirm what I suspected and that is that the window channel has a slight "dog-leg" inward at the rear and above the bottom of the window opening. It is obvious that the door has been repaired sometime in the past such that the door frame the window channel rests against has been moved inward. I am going to remove the window channel and the glass/glass channel assembly to see what can be done to get the surfaces for the window channel lined up. Thanks, Norris.

I hadn't considered that the door, itself, may be bent, Norris. It wouldn't take much to pinch the glass. I suppose you could use a port-a-power to spring the opening back a bit. Be sure the fuzzy channels are fully seated in the door. We often use small pop rivets to pull the channels tightly to the frame. New ones usually come coiled, and it is a big job to get them straight enough to get the glass to slide easily.

Thanks Bob! I am going to get a piece of cold rolled bar stock the same outside dimensions as the window channel. This should let me know when I have alignment. Norris
