Just purchased one of these for mounting a seat on a 2004 Lowe Roughneck. The Roughneck has 0.35 welded access bracket running along the entire upper edge of the bow-side of the seat bench. This item is pictured as having no vertical metal segment so I believed it would work. WRONG, the bracket that was shipped has angle aluminum on the forward edge and cannot be used because the top screws will too far forward. Fortunately I have another boat that I can use the bracket on.
