I have a cmc pl-65, manual jackplate. This one has 4 nuts on the adjusting screw, on either side of the bottom plate, and the 4 on the sides. There isn't a nut on the top of the adjusting screw. Can i put one on it? To make it easier to adjust. Tac weld? Drill, tap, set screw? Add a jam nut?
What would i do with the 4 nuts on the adjusting screw?
