Rob - Sorry I don't have any pics of this. When you pull your mast you'll see an oval that is screwed to the deck. The mast extrusion fits snug over this oval and prevents the mast base from moving. You should be able draw a line 1 inch back from the forward edge of the molded step the mast sits on. Measure the thickness of the mast extrusion and draw another line behind it. This is where the front of the oval that is screwed to the deck should be positioned. Once everything is reassembled, the distance from the forward edge of the mast to the forward edge of the molded step should be 1 inch for best class legal rig tuning.
