I got home after driving around and took some more photos and measurements.
So here is the car.
On 235/60x15 BFGs set at 32 PSI, with a spare tire in the trunk and a full tank of gas, she sits about 27-3/4" tall at the wheel well in the front and 28-3/8" tall in the rear.
So the new coils dropped the front exactly an inch from the generic coils original measurements. The 1" de-arched leafs dropped the rear two inches from the 30-1/2" 4x4 look with the generic leaf springs, to 28-3/8" tall with the de-arched Stengal Bros springs.
For comparison, the measurements on my 114,000 mile, 72 T/A with its original 3988100 AX code, front coils, and PL481612 rear leafs sitting on F60x15 Polyglas GTs with 32 PSI, was measured at 27-1/4" tall front and 28-1/4" in the rear. (My Formula was ordered with the T/A suspension option which would have been these exact springs.)
So, I am happy with the way she sits now. Maybe after a thousand miles or two, she will settle another 1/4" or so. I will definitely say that she does ride beautifully on the new springs and the KYB Gas-Adjust shocks.
