Cj7 frame ground clearance question

I need some help. I am trying to determine once and for all what the stock FRAME RAIL ground clearance was for my '77 CJ.

In the chart below, all the measurements for the side view of the frame are from a DATUM LINE and not ground level. This makes sense because different sized wheels & tires would affect actual ground clearance. Does anyone know where that datum line is set? Is it for example set at 7 1/2 inches below the center of the axles? (15 inch wheel was stock, 7 1/2 inches would equal the bottom of the rim.)

Does anyone know? Or does anyone know offhand just what the actual measurement of what measurement "A" or "D" equals? Or measurement "C"? (center of the hole for the rear spring mount)


Paved roads are just for getting you to the starting point!

Don't know for sure, but it would make sense to me that the measurements would be based from the center of the axle
