Today was finishing up installing the Mid Seat Rail Support. I used some stubby wrenches including a stubby flex head ratcheting wrench which was probably the most useful. I elected to install the bolts from the bottom as trying to start a nut and washer on the bottom would be most difficult. I even used a Popsicle stick with some two-sided tape to help position the bolts from the bottom. With the stubby wrenches it all went very smoothly.
