I moved on to the Top slide rail since it was just clecoed in two places. I finished drilling the 6 holes to receive the counter sunk bolt. These need to be a little under the surface or they will hit the slide as it moves over the heads. I figured it should be just a little under. 5 bolts go through the top skin and the center stiffner and receive washers and nuts. I will probably remove it later for painting.
