4-Speed hump on a 1974?

johnparts said
Ok I was looking at my floorpan the other night and I noticed I have a small hump on the floor with some locator holes to mount or drill through. Am I missing something I though if you had a 4-speed you needed a new tunnel?

johnparts, the small hump is there for the floor shift linkage vertical shaft with the auto console. This is not for the 4-speed manual shift.
