Hydro turf works well. Make sure you cut strips wide enough to lap all the way around the bottom of the rail to use that flat surface, as well as the top, for adhesion.
H14's dont have (need) non-skid on the rails in front of the chain plate for the side stay, that's pitchpole territory. At least that's the way the factory kits were sold. Looks funny compared to a H16, as you say, like somethings missing.
