I removed the drive without doing steps 15 and 16. I was able to pry it out with a little bit of force and then I installed an SSD. There is enough room for the hard to come out if you just nudge it out. Someone suggested using foam to make up for the 2.5mm difference in thickness. I used a piece of paper that I folded 3 or 4 times and then taped it to the SSD. The SSD slid in with no problem.
