Finishing up my Basstracker project. I can't seem to figure out how to mount the seats for passenger and driver. Screws are to short to mount directly to the wood. So I bought swivel brackets, but how do get them together without being a contortionist. I mounted the brackets onto the seats but its awful tight trying to get screws through the wood and achored? Should the bolts be on the bracket side or under the board of the seat? Am I making this more difficult than it should be?
