We don't have Verne's expertise to lean on anymore (RIP) but I believe power brakes did not come on the '63 Z11s and all of them had the plenum air cleaner so it would stand to reason that there should be a hole in the firewall for that or at least a plate covering it up.

I have Rusty Symmes "Project Z-11" book and when I get a moment I will look through it and see if there is any reference to that. Perhaps Rusty may know the answer.
