How does somebody know what type of hump to order a mat for? When I was buying my carpet, I ordered it from Classic Industries, and the choices included low hump and high hump TH400. Since I have a TH400 I thought that means I need the high hump TH400 choice so I ordered it. 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.
