On the profile of the 1914 Touring, does the rear top bow overhang the back of the car and if so, by how much?
No, straight up and down.
Yes. Approximately 2 5\8".

It's for a '15, but the dimensions are basically the same.
I like straight up and down. Look at Bruce's book, Model T Ford, the car that... pg. 188. It looks straight up and down to me. I will do mine straight up and down right or wrong, lol.
The link I posted is for what I believe is a Ford dimensioned drawing.
However, I'm a true believer in whoever has the title and the funds, get's to do it whatever the way they want it.
When you're building cars as fast and as cheap as Henry built 'em, I'm sure they came all different ways. No time for measuring. The Rip Van Winkle car proved that.
The rear curtain of the top should roughly follow the line of trajectory from the back of the back seat, so the rear bow should overhang the back of the car.
The top will shrink in time and the rear curtain will take on a more vertical appearance.
Keith has made a good point. The top will shrink over time and the back bow will be pulled forward. To my eye, a forward leaning back panel makes the car look hunched up. If you start vertical, the shrinking top will drag the bow forward to give this hunched look. His "line of trajectory" following the back panel is about right. I use a plumb line from the top bow and measure 1 1/2" at the top of the back panel. This is one time when more is better than too little.
Hope this helps.

Originally the rear bow hangs over the rear about 1". It won't move forward when the top shrinks because the rear straps won't let it move forward.
Mike is right; that's the overhang according to the Ford print of the 1914 top.
I stated that on p. 188 it looked to be straight up and down. I looked at it again and I believe it does have overhang, so when I do mine I will give it some overhang, but will use a plumb line and perhaps some guessing until I am happy with the look.
