'40 coupe - installing little side windows

[fordman]

soon I will be installing the little side-windows (the triangular ones) and I am asking for your comments so I can do this correctly (the first time)

thanks for sharing your experience and knowledge,

These are perhaps the easiest pieces to install in your coupe sans the 1/4 pieces.
Remove the old glass, clean the channel, line the new glass with the correct thickness of glass setting tape and push the new glass in to the channel.
You may need a rubber mallet to help it along.
I prefer that the frame is out of the car but this can be done when they are intact of the window bezel. Be certain you do not "spread" the channel.
You may use a little glass cleaner as a lubricant if you like.

I'm guessing that fordman is talking about the quarter windows.

That occurred to me too. He may in the future try to be more specific.
I went with the wind wings as the 1/4 windows really don't demand any explanation as to how to install them. Those are pretty much "take off the window bezel, remove the old glass & rubber seal. Then, install the new glass with seal and reinstall the bezel. The only caveat on the side windows is glass thickness. New glass is typically about .015 - .020" thinner than the original. That's enough to not make a good seal and requires some innovation. When I have been forced to use less than accurate glass, I've added setting tape to the glass prior to installing the rubber seal. Just enough tape to bring the total thickness to the specified .250".

Here's some additional info.

I was thinking about the little quarter-windows on the side behind the front seat, but I will need all of this information. thanks!

Working with glass, I've been working my way from the back-to-the-front; finally planning to do the windshield last.

Fordman... these are, as I stated previously, the easiest to replace. Just be certain the check the glass thickness. It should be a nominal 1/4". If not, shim the rubber seal with glass setting tape. If you don't, the window will rattle and not seal well.

I checked on NAPA's tube recommended by 19fordy; that product is discontinued. What glue do you recommend between the rubber seal and the body? One that can be cleaned up and not damage the paint. The glass is from Sander's and the seals are from Drake; I have already installed the glass in the seals.

Because of other recommendations I am avoiding silicones.

thank you,

Sealant is not necessary. I would suggest glass setting tape on the glass edge to get to the nominal .250" thickness as original.
Sanders glass is typically much thinner than .250" and must be "built up" for the seal to work properly.
You may also utilize friction tape available at any hardware store for about $1 a roll.

The new part # for the Napa sealant is 4121 and it is still available. If you use sealant put masking tape around the edge of the rubber seals and then use the sealant. It makes cleanup so much easier. I have found that you do need to use sealant if you drive your car in inclement weather. I also seal around the trim clips on the inside where they pass through the body. Water will come in around these clips and get inside the car. I have found that the factory used some sort of sealant on their windows when I removed original glass from cars..

The factory did not use sealant, at least not in '39 - '40. What you may think is sealant is the deteriorated (old) seals or perhaps the glass was swapped out in the past decades and then sealant was utilized.
Properly installed glass of the correct thickness with good quality seals is all that is required.
Ford did in fact apply a bit of "tar" around the trim clips.
