Door glass dimensions

I have a 65 4dht and am having a real issue with the door glass not going all the way up on all 4 doors. When I force the windows up as far as they'll go, the rail that the glass is bolted to pushs up through the weatherstripping. Also the front glass does not go back far enough to engage the rubber stripping between front and back glass. After months of on-again off-again working with this, it occurred to me that maybe a previous owner put glass from a 4 dr sedan in this car because those windows would be smaller due to the window frame on a sedan. Does anyone know the glass dimension on both of these models so I can compare?

Does your present glass have Chrome Metal Trim around it?

A picture would also help if possible.

Glass flows with time (it is a super cooled liquid), but the effect takes centuries, not decades to notice this.

If your windows are not going all the way up then your doors are going down. Your problem is with worn out door hinges and the striker plate, not the roof rising or the glass shrinking.

In the case of the front doors, the vent window frames sit correctly in the door opening making good contact with the roof rail rubber however the windows stop 1/2 to 3/4 inch from the top of the vent window frame.

Im'm having difficulty attaching the photos but will keep trying.

Where the window mechanism bolts inside the door shell has adjustment, but not a half inch or more. Something is wrong in terms of the parts that move not the glass itself. Door sag is the first thing I would address (keep in mind the vent window also bolts in and can be adjusted down and the door moved up).

The doors don't have any sag to them. The hinges and pins are new and door gaps are right so that's why I started looking at glass size. I've replaced all the regulator rollers and re-installed everything, adjusting it as I went. I will look at the vent window adjustment again but am not sure how that will correct the situation if I lower it to match the glass. Thanks Dave.

I was at a cruise in with my 65 4 door hardtop and a 65 4 door sedan parked next to me. I noticed right away that his windows had rounded corners. For what I could tell the glass would not fit well at all in a hardtop.

Didn't get a great picture but the glass is definitely smaller in the sedan and the top rear is rounded instead of hard angle like the hard top.

yeah mine aren't rounded in the back corner. That's good info though. Guess I'll just tear them apart and start over. Thanks AngryForest
