Molded Carpet or Regular Carpet

Do they make a one piece for a-bodies? I only recall seeing the 2-piece. I thought OP was talking about carpet off a roll like for your house. My Duster carpet is 2 piece with finished edge at the overlap, but is heat molded and has the backing pads under all foot areas and rubber heel mat at driver. I did a Nova with roll carpet from a carpet store a very long time ago. Don't recall if that floor was any flatter than the Duster. Results were not terrible, but not even close to getting one fit for the car. I think you will pay more in aggravation than you save in $.
