This is a subject that has been troubling me for some time, and anyone with cars in the '22 -'24 era with original tops would be of help on this. 80% of the cars of this era that I have seen have the window size incorrect, and the placement on the rear curtain too. The '17-'21 open cars are in the same boat. Next, back to the later style, are the roadster and touring window sizes the same?
This sketch is from Model T Times issue with ref. to the approximate rear window locations for the gypsy style rear curtain of the '22-'24 and later '24-'25.
Have seen original tops with similar locations, and some believe the runabout may have closer together rear window distance between the 2 windows.
But looking at old photos of the slant stanchion T's show about the same width of material between the windows on the runabout and touring.
The photo below shows a '24 style on left, and the '23 low radiator style on the right, both are similar placement to the sketch.
By this time Ford was making all its own tops and side curtains, so factory methods would assume window style and locations were constant.
So the only variable perhaps in the location from the rear body edge would be the assembly line trimmer's work
Note similar placement on different body styles.
This runabout seems to have wider gap.
This runabout seems to have a more narrow gap.
Thanks Dan. I still would like to know if the roadster and touring used the same size windows?
