Only low hump floors are made.You can cut and install a high hump,though.

Two wheel drive floor pan vs four wheel drive floor pan? Are they the same?

The pans are the same and interchangeable.Only the hump itself is different.As 68350 said,all 4wds had high-hump and only big block or 4spd 2wds did.But,the impression is there for the bolting surface of the high hump.GM offered replacement cabs for a while,but only non-air low-hump.Instructions were included for adapting for both a/c and high-hump.

So this one is unfortunately a low-hump? And I would need a tall hump?
