No, I read what you posted, and in my experience replacing rubber with uerethane made no difference. When I restored my 70 3/4 ton, I put brand new rubber cab mounts in, about 3-4 years later I put the urethane mounts under the cab, and the truck rode exactly the same. Now the back of the cab doesn't get dented anymore from the bed hitting it. Suspension mods could/would make the truck ride smoother, but cab mounts won't. I'm planning on doing longer springs under my truck to try get a better ride.
