Floorboard mat (1) with interlocking base GU18447050

One rubber floorboard mat with tall ridges and big interlocking grooves on bottom side. These unusual mats were used on 1990's California III Classic models and was occassionally used on some others, likely depending on the whims of Guzzi. The difference between this mat and the more common flat mats is that this foot board mat has deep grooves in the bottom that interlock with metal ridges found on some floorboards, and, the top side of the mat has tall ridges, with deeper valleys between them. See alternate 13447040 for comparison.
