There was enough room for me to add a 2x12 board under the carpet at the hump location, so I guess I got the wrong carpet. I like it anyway and now it appears I have a high hump with the board build-up. Are there 3 different hump heights with a 3 on the tree transmission and TH400 automatic are different or just two different heights in these trucks? When I wear out this carpet I think I will change to one of those vinyl mats like Bruce88 put in.

A couple threads that should help:
