My husband made a cute female anatomy comment, but that wasn't much help.
Thanks guys... Lori

the large hump is for the 4 speed floor shifter, the small hump is for the column mounted shifter.

The high hump is an abrupt transition up approximately 6" over the tranny. The height of the cover is relative to the factory equipped transmission, however, if your tranny has been changed, you may have a low hump with a floor shift automatic transmission or an automatic in a factory equipped four speed tranny truck with a high hump.
I hope this helps.
