No, there are lots more differences. Use a hex editor program that can compare the bins and you will see them all. The data is the first half, where the differences will be, the code is the second half and is the same.
That was a really good read. I especially like to see explanations of information like you included in this document. I had already (since suggested above) compared all the changes bit by bit, but this helps me understand why they were made by Buick.
