I know this can't be some home done hack job because these holes are really done with some precision. They are consistent and equal, the edges feel like they were punched or pressed out and not sawed out.
The heater I have came with the car but in another thread where someone posted having the same type, it was clear that the vent controls and register for this were part of the floorboard and not part of the firewall.
Doies anyone have any idea what should go here????
Woops, the forum isn't allowing me to post pics.
Here are links to the pics.
See where they are? Just behind and to the right of the exhaust manifold.
If I remember correctly the lower hole is a speedometer cable hole. I need to go look at my Touring car to be sure though. I doubt that either is heater related.
I just want to add that Ford did not place a hole in the metal firewall to accept a speedometer cable. The wood floorboard was notched, and if the Model T had engine pans, the cable went through the hole for the carburetor drain. This is documented in the installation procedures published by Stewart Warner. Hope this helps. Russ Furstnow
No sir I know this is all accessory stuff and done aftermarket. I just wonder what for?
Everyone else I know who have things like this have it usually run thorugh saw cut rough holes. This one you can feel where it was pressed out and very neatly done. Too high to be a foot pedal for something.
I'm gonna forward Jay the link for this. He might know.
I notice your choke bellcrank is bolted on instead of being riveted. Could this have been a replacement firewall that also has provisions to fit the linkage for 26-27 carburetors and vaporizers?
Here's a couple pics on firewalls.
This one below is an early metal low firewall (1923), prior to the dash brace on the instrument panel. No extra holes or that elongated 'slot'.
But by 1924, the elongated 'slot' was added. The pic below is my late 1924, still with 3 dip pan.
Now you can see that the firewall has that added elongated or oval hole.
Mine even has the very rare Part # 345BBT rubber oval gasket with the slot for use with the
Mine also has the holes as described above, and it's a 24-25.
I had a look at my '24 Touring. It does not have the slot or hole in its firewall.
Neat! So I wonder what could have gone here?????
Along the lines of what Tom said, could these be replacment firewalls that covered all years?
Do the improved car carbs have linkages this low???
Patrick, I by any stretch am not an expert, but I am inclined to agree with Tom. I have found MANY low steel firewalls over the years. There were surely many of the wood firewalls replaced over the years since the original production used the steel ones for such a short time. I have six or seven of them now I think. Dave
So are these for a later carb?????
and if so why would the holes be so large????
I have seen that hole before and wondered the same thing. It's too small to get the speedo cable through.
I checked the metal firewall on my 1924 Tudor (February 1924 build date), which has never been disassembled or restored, and it has no holes. This car has the "high" firewall. Hope this helps, Russ Furstnow
I always thought that hole was on the 25 firewalls but apparently not. I just looked at my June 1924 Coupe and it has the hole - along with the four rivet data plate. I have no idea what it is for. There is also another small hole in the top of the protrusion where it covers the back of the head. You can see it as a white spot in the second photo Dan posted - just to the right of the carb rod. I think I heard at some point a hole was added to hang it for painting????
No hole on my 25 tudor firewall in that location...Rick
