Thanks to some detail provided by Fish'n Jim I found the reason for my problem of test piece being too narrow. No overall shrinkage, just broken and worn off rubber on the originals. There is a rounded top edge on the outside rib and what I call a lip at the bottom. Adding that should account for a missing 1/16". The rest was some of the inside tapered width of rubber that goes up to and under the stainless piece was missing. Adding 1/4 there will account for the rest of the missing width and allow a bit of trim area to fine tune the fit.
