If it is bolted in, it is a hi-hump.

wideside, that's not how it went.

4x4 trucks... high hump
4 speeds... high hump
big block with automatic... high hump
All others, got the low hump.
There were a handfull that got a high hump and shouldn't have, but what I typed was what GM said.

If the hump is missing, you will need a hi-hump. A low hump is part of the floor.
