Carpeting for 69 Barracuda Fastback

I have learned through the years to have the carpet cut long. The sales department assistance that I use will always modify the order to leave extra material on the sides and top. Otherwise, it will be cut tight to the pinch welds and not give you much to work with. Much rather have to deal with cutting a little off, vs. having a wrinkle that is not giving you any extra to work with.
