Product review (5 stars): Watch the YouTube video for "W10712394 V-rail"
This would have been 4 stars due to poor installation instructions. I give five because the Amazon kit included an adapter to turn my phillips head screwdriver into a torx screwdriver, a real help.

I overcame the poor instructions by combining the printed page with a YouTube Video. You can find the video by typing "W10712394 V-rail" into the YouTube Search bar. There is a one digit difference in the part number but, I could not see any differences between the video and the kit I was installing. The video says that you need a torx screwdriver, but the adapter provided in the Amazon kit does the job.

The pictures on the printed instructions are not clear. It is so much easier to start and stop the video as you go along and have large bright images of the work. The video is an immediate help because the instructions start with a one sentence instruction to remove the old parts. No photos, no steps, zip. Yes, you can just rip them out, but it's better to do it right.  In particular, installing the rack clips is easier when you can see the orientation of the part in the video.

About 30 minutes start to finish.
