I had a really stiff ride with my 30 CCPU a few years also, so a sprayed penetrating oil on the front and rear springs. It helped. It was only a temporary fix. So, this spring I decided to fix the hard ride once and for all. I bought a new front spring and a 7 leaf roadster rear spring. Disassembled both springs and painted the contact surfaces with graphite paint and rounded the lower edges of the ends of the individual leaves. My final step was replacing the worn out aftermarket arm style shocks with a set from Bill Stipe. Hard ride problem solved. Be advised that all Model A car styles had the same front leaf spring. Also, you said you removed two leaves from the rear spring. IMO, Softening the ride will be achieved by changing/modifying the rear spring.The Model A 10 leaf truck spring has a thicker main leaf then all the other models. So by removing a couple of leaves, you did make the ride softer. but it's still firmer that a standard 8 leaf spring.
