The only reason I didn't give 5 stars is because the 2 mounting holes are 3 1/4" apart. fastens 3 1/2" wide. On both sides There is only an eighth of an inch left of the mounting screws to attach to the skin strips, so the only way to use these mounts was to drill another hole between the two existing holes to ensure that each of the two mounting screws seated securely in the strips of skin underneath.
