I am making progress on my 48, I'm trying to find a high quality carpet kit that fits the 4 speed with the original seat riser. I would like it to include carpet under the seat and for the back wall. My trucks gas tank isn't in the cab so no need to worry about that. Any suggestions would be great. I checked stock interiors and all they have is low hump, I believe that is for the column shift and the high hump is for the 4 speed.
