Just purchased the deck extension from Ranger. As has been posted elsewhere. No instructions included. I would like some advise on the brackets that came with the extension. There are four. "L" Brackets, which I assume are screwed to the bottom of the extension, 4 small flat plates that are screwed to the sides of the rod box and cooler, and 4 thumb screws that goes through both. I would like to see pics of someones brackets and how they are installed. If my assumption is correct, two on the cooler back, one on either rod box. Also, it appears that in addition to drilling for the two screws in the small plate, the center must be drilled to allow the thumb screw to fully tighten. I would really appreciate any advice before I start drilling.
