Yesterday I purchased the wood for my floor boards. I used that to cut and fit bothe left and right floor boards. I got the left one drilled and nutclips installed. i used a laser pointer to point the center of the floor tab then installed the floor board. All that was left was to drill on the dot. The technique worked well the toughest thing was to get the pointer secured and steady while reinstalling the floro board. The right one is fit and will be drilled next chance I get.
