The name, as you asked, is a play on words. Americans have a very difficult time with the German “PFs”. Last name Pfaff, plus my career as an airline pilot equals pflyer. My ‘78 euro 635csi had the license plate pfast. In’83, I modified the engine to where it had well over 300hp, hence the plate. Is the front non-sunroof headliner still available? Also to the support rods and hardware that you mentioned before? Dave.
