I have a '65 Pontiac-built Chevy C80. In comparing pictures, mine has different handwriting but does have an "Ewt" in the trans tunnel, similar to your "Ewa" or "Ewq". I don't know what it means either.

It also has a seven digit number. I looked it up and it turns out to be a speedo cable p/n. The p/n is applicable to the truck. I guess it needed to be loaded from the bottom side and it was convenient to notify the operator that way.
