Holes not lined up on Universal Housing

[Diastole]

I purchased a early 1930 Coupe, oval speedometer. The engine has been swapped for an April 1929 motor prior to my ownership. Alas, the former owner passed away and his wife has little knowledge of her husband's car.

As I am trying to improve some of the coupe's shortcomings and repair misadventures I am ready to tackle the franken-chassis that is her clamshell. As you can see from the pics, the bottom hole does not line up. Five of the six holes match. Can anyone help me with a diagnosis and possibly a solution?

In the article "Authentically Speaking, Edward Francais and George DeAngelis discuss the holes at 2 and 10 o'clock being misaligned not 6 o'clock. See Photo. And, this article discussed the first 1,000 Model A's. Not this vehicle.

The Clamshell does not leak anymore than normal, and the car runs.

Is there a solution?
Any concerns with driving this car?

Any help would be greatly appreciated.
