Leaf spring re-arching.
You can use those measurements from Stengel (Stanley Spring) to get the arch loaded if you know the weight on the springs.
@autoxcuda and I concluded they are using the term spring capacity to indicate load that will bring the arch to zero.
Don't think I called them to confirm that but it cross referenced with some info we had on a few specific spring packs.
We can also calculate the spring rates.
The standard leaf springs have a spring rate around 85 lbs/in (530 divided by 6.25), & (620 / 7.125)
and the Heavy 6 springs have a rate around 114 lb/in (600/5.25)
If you can drive the car up on a scale, and then pull forward so the rear wheels alone are on the scale, you'll know approximately the weight on the springs. You'll haveto estimate the axle wieght.
Or, if you have the springs off the car, you can apply weight and measure how far they move. If you do this by standing on them, have something to hold on to when getting on and off. ;)
As far as the heights in the HH archives documents, maybe @Alaskan_TA will know more about the measuring points.
The five passengers etc should bring the car close to maximum weight allowed. That will be in the owners manual and shop manual.
Correct.
