Low Hump in a 4x4?

[Nova70]

Well I crawled up under the truck to see what kind of clearance..... I don't know why the previous owner put a high hump in it? It has PLENTY of clearance from everything. He only cut out a small section of the original low hump and then bolted the high hump in. I think it was to clear the floor shifter that's in there. It's the only thing I can even see that would cause interference. It's a turbo-350 and a 205 transfer case. I'm going to a low hump when I do my floor pans.
