I have a 66 hump that is not buggered up. I can get some photos/measurements if it will help determine what you have. I tend to agree with @66340SEDAN that they both look like 64-65 and the brown one was hogged out.

I'm good. It has the exact floor measurements as the 64-65 floor hump. I believe it may be a 65 as well.
