I am replacing the glass in my 1927 coupe. I have taken the pieces to my glass shop. What I need help with is the size of right door glass.

The left side of the glass measures 19 inches and the right side measures 19 3/8 inches. As shown on the attached photo of the glass specifications, the right side should measure 19 7/8". The shop is ready to send templates out to get new tempered glass and has asked me what dimension should they use.

The glass is shown in the attached photo. Note that it has a vertical crack in the middle.

I am thinking we should make it to the specification dimension. What are your thoughts?

Why not take a piece of cardboard and cut it to fit in each window channel so you get an accurate size? One of the windows could have been replaced in the past and not cut properly. If you make a cardboard template of each window, then you know the new windows will fit.

Bruce, if the windows fit fine in the door before you took them out, then there is no reason to make the new glass any different than the old glass.

The dimensions on the paper are the correct FORD dimensions.

As suggested, you really should make a cardboard cutout to the FORD dimensions and fit into the door channel. Now, my guess is that the door channel is completely out of the door and this cannot actually happen. If that is the case, then you should wait until the car is painted, the door is reassembled, and the channel is in place. At that point, you will likely find that the FORD specification fits more correctly than the glass that you have does (you do not know for certain the pedigree of that glass, particularly since it varies from the spec).

Now, when you refer to "right" and "left" you're referring to the picture, but in fact, it is "forward facing" and "rearward facing". You need to figure out which is which so that the glass is fit correctly in the channel.

Finally, what is the dimension of the glass on the left/driver's side? That will likely match the FORD drawing.
