For Step 8 have the correct tools. The little screws (one on each side) are upside down and there is not a lot of space between the car and the screw head. It was a little weird to get these off due to the postioning and would be easier with a 2nd person (your son?) holding up the rails for you, but can be done solo.
The DIY mentions using needle nose pliers, another member used a small vice grip, but I used and ratcheting offset screwdriver I purchased at Lowe's for under $5.
for some other small hints I found helpful when I did mine see
