Marzach, as promised I measured my old on tonight and it measures
1 5/8" x 3" x 2 3/8"

The rubber pad attached to it is 3/16" thick but does not cover the entire block of wood. Over the years they probably flattened out a little.
For my "cushions" I cut up an old fire hose that I accumulated as it has a "polyester" cover with rubber inside. I figured they would never rot and hold up nicely.

My new blocks

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
