This is a picture of my car which is as it was when I got it. This is a March '34 car. It definitely had a vacuum wiper motor as it came with it and the inside bits of the pipe were still there.
There is no hole near the glovebox though, other than the one the choke wire comes though lower down. You can see others are used for the original wiring, speedo cable and oil pressure pipe. There is another hole behind the head / block on the bulkhead but it looks like it was chewed out, so I'm suspecting not orignal.
