It will be the same thing as in the past... they won't make the correct battery, because everyone still buys the other one.
When the choices are limited, folks have to take the best available.
I have an assembly line 22F that I'm exploring 3D printing options. Will be a couple months before I have a prototype.
The 22F probably came in 90% plus of all 65-66 cars and then in 67, the 24F was probably more predominant.
For the 24F 65-67 assembly line style, I might be able to create a 3D file based off of details from the 22F.
