Tallest part of the car is right above drivers head (aren't they all?). Behind the driver is 6 feet.

What is drop in car of the first 2 feet behind driver's head? Next 2 feet? Final 2 feet?

I want to do the sides also. Widest part of the car is at the driver's elbows (aren't they all?). which is 40 inches wide. Need the same numbers.

Your car is half scale of my trailer. I took the image of the template, scaled it to fit in irfanview, and made some prints till it would measure up with an engineering scale.
I scaled your car as follows:
10% = 15.3" aft = 44.7" = 3.5° slope
20% = 30.6" aft = 43" = 7.5° slope
30% = 45.9" aft = 40.75" = 12° slope
40% = 61.2" aft = 37" = 15° slope
50% = 76.5" aft = 32.25" = 18.5° slope
60% = 92" aft = 26.7" = 21° slope

Looking at that, I would move the highest point forward of "right over the driver's head".
The headroom does not lessen appreciably in that first 10%. I'd put the 10% point over the driver to maximize headroom when you lean forward to get out, and maximize the drag reduction at the back.
You get back to that ~20° slope which is near maximum.
