Firewall hole
Wondering about this rather large oval hole in my ‘25 Coupe firewall passenger side. Is it for a speedometer cable? Maybe it lets heat in? It’s not for carb adjusting rod, that fits elsewhere.

This is my unrestored 1924 runabout, it has the same unused hole.

Re: Firewall hole
My guess is that there was a “transition” happening to the carb controls!

Re: Firewall hole
One of those things that over the years people have wondered about. 
Too small for the speedometer cable and it's just there. Think they were on the low radiator metal firewalls too.

Re: Firewall hole
It is for the later version with the swivel top carburetor control rod. Here is a picture of my 25 roadster pick up.

Re: Firewall hole
Sort of typical what Ford would do to keep the transition of cars and their parts going to the next models.
Changes in the fender bracket holes in the frames, updating fender brackets, battery bracket holes, open car windshield brackets and etc The firewall updates also as we see here. I have a 24 Coupe and wandered about the extra hole too. Learning about Model T’s and finding out things were transitioning all the time. And the assembly just kept moving along!
By the way I used the extra hole to attach one end of a cut down screen door spring and the other end to the arm of the carburetor choke arm. The carb choke plate arm spring was broke and attaching the spring end to the arm worked pretty good when I choked the carb!
