Very nice hearing from you.
Back in 1975, I met a gentleman that just bought a 1952 Buick Roadmaster sedan from the original owner. That Buick had 48,000 miles on it. He took me for a ride, and even let me drive it! It rode very different than the 48. The suspension was a little stiffer, the shocks were exactly the same. The springs were stiffer but had a very good smooth ride at the same time. Whatever Buick changed in the suspension, was in the right direction.
