Mounts on a 13 foot Gorilla MPX Multi ladder which has a much thinner outer wall material than my Little Giant 1AA Super Duty. Using the shortest bolts up near the flare proved too long. The new assembly will not slide past the bottom rung of the existing ladder. Cut 3/16" off in a vise and use a 5/16" coarse die to clean it up. Problem solved. The outer bottom of this ladder doesn't need a washer (it's flat - doesn't wobble).
