Hi Stampede, you are correct on the stray lines in my version 1 of the diagram. They were left over from when I was working on some other measurements and I inadvertently left them in yesterday. I noticed that this morning and deleted them when I updated the image to version 2 earlier today.One problem I see with your height estimates is the line drawn from the top of the rear tire down toward the wheel of the front ... not on the same ray/perspective path as the line drawn along the bottoms of both tires.
When I was initially looking at the angler ladder measurements I found them to not be as accurate due to the parallax. I found out one of my most accurate measurements is shown by the blue line from the second step over to the bottom of the frame, the second step is 17.5" high on a flat surface. I cross checked this by the vertical red line from the ground to the frame, it also measures 17.5", so the match was good confirmation.
Unfortunately doing these scale measurements on the Bronco when the photo was taken at an angle makes the horizontal angles inaccurate for measurements while the vertical measurements allow a higher degree of accuracy. For example, I attempted to measure the wheelbase, trying to confirm the 110"-112" that was estimated by others, I got 48", so you can see how much error the angled photo introduces. Hopefully someone on the forum has access to some geometric tools that may allow them to properly calculate things like wheelbase.
That is a nice ray trace diagram and an interesting observation about the aerodynamics, you have a good eye.It also appears that the body lines and those of the geometrically symetrical tires do not converge at the same point. If the designers gave it a slightly nose down stance for aerodynamics that would make sense.
