My truck was a low hump as you can see in this picture. Some of the 60-66 floors cam with a bolt in low hump and some had a solid formed floor.
Captnfab: In my application the spot welded front section of the low hump has to be changed, it is a different shape than the weld in high hump front section. see pics below.
