New carpet next to the old one for comparison. This is just a test piece as the cut pile option no longer has graphite available to match the old carpet. The original carpet had alot more padding under it too, the Vert seemed to have twice as much. Its just a basic carpet pad easily found anywhere they sell carpet.
This task is going to be alot like laying carpet on a spindle staircase with a shift lever and at least 20+ bolt and clip holes/slits that will need to line up perfectly or you`ll have lumps and wrinkles.
