Sorry, 51.2 Ton

My link was to a page in the 1929-1957 Master Parts Catalog.

It shows that the 4-speed mat was standard for the big trucks that had standard 4-speed transmission.
It shows there was a different floor mat for Suburbans.

Maybe someone knows a source for a floor mat for a 4-speed transmission?
One vendor suggests the buyer cutting the "standard" mat to fit the 4-speed. I think that is what I dids in my Suburban?
