Thanks for the input Bob, I am not saying that is why its missing, just seems odd almost the exact same issue in both cars of the same year and possible build location.
The top over hanging piece of the large pad I am guessing is pretty flimsy at best so if it gets damaged or torn at all during assembly of the steering column or other components and if already mounted ans secured on the firewall it would be easiest to just tear off rather than replace the entire pad. I don't see any other reason why this damage would occur later to much stuff in the way, but may have, guess we will never know.
