What are these holes in the firewall for?
The firewall that came with my stripped chassis is a reproduction and I am looking to buy an original firewall. I have no idea what these 2 holes are for on the passenger side. Can anyone tell me? 1925 Roadster.

Re: What are these holes in the firewall for?
The 25's used the same choke/mixture single control rod as the improved T's. Before this the choke rod was much further up on the F/W attached to a riveted on bell crank. So, I can confirm what it is not, but not what it is. This looks like a job for Original Smith.

Might vary by year, not Ford supplied holes as far as I know.

Re: What are these holes in the firewall for?
Rich posted pictures that are instructive. I cant tell for sure, but, that hole could be for the single mixture/choke rod.
The firewall has the earlier separate choke bell crank & mixture holes also. Transition?
Humble J's looks to be a 24, early 25? style F/W with the separate controls.

Re: What are these holes in the firewall for?

Re: What are these holes in the firewall for?
This is my 1925 roadster I picked up last fall. Engine # puts it the first few days of May 1925. From what I've read the late 25 to 26/27 used the choke rod without the bell crank similar to the later Model A setup. On mine I think someone tried to convert it to the newer setup as the bottom hole was enlarged and the choke rod has a section welded on and the end squared up to fit the u-joint setup (choke rod sleeve and wire were missing). I'm in the process of putting it back to the bell crank style. Just waiting on some parts now.

Re: What are these holes in the firewall for?
Update, and more mystery. I checked my unrestored 1924 roadster firewall and it has those 2 holes with nothing going thru them. My choke and mixture go thru other holes in the firewall and spedo cable goes thru the floorboard. The floorboard has a relief area to clear the holes.

Re: What are these holes in the firewall for?
The rust makes it difficult to identify. Does that firewall have four holes for the patent plate or two? Two is a 1925. Late 1925 firewalls have no bell crank for the carburetor, but the two holes for it are still there.
