A few more helpful hints now that I just completed the job again on a different bike.
The wood screw /bolt mounted on the seat is in the center hole of the bracket and is mounted into the center of that little rectangular hump you will see on the bottom very rear of the seat. Later, I added a small long screw to the last hole of the bracket as well, so the bracket cannot move at all when putting the seat back on. This screw just barely goes into the plasctic under the seat.
Notice on the loose bracket in photo, when mounted on the rack, the part that holds the clevis pin will be flipped up toward the rear of the rack. This bracket will use the very first two holes in the very front of the rack, with the clevis pin more to the rear. The holes on this bracket will line up well enough with the rack for the machine screws with washers and nuts.
When you start doing the job, it will be fairly obvious what to do before you drill a hole into the seat, as long as you start with the part that mounts under the rack.
Entire job took me less than an hour. It's an easy job that goes smoothly all the way.
