Missing parts from 2016 kit

Hello - My daughter received a GoPiGo starter kit in 2016 for Christmas. She showed no interest in assembling it until this summer. Unfortunately, when we opened it tonight, parts were missing. We printed off the directions for the Raspberry Pi Robot car and here is what we could not find: 2 motor cables, 2 metal motor brackets, 1 small screwdriver, 2 short silver pots, 10 mini screws, 6 gold posts, 1 short screw, 1 nut, 2 long screws, 1 medium silver posts, 1 long silver post. I also noticed our large acrylic piece looks different from the picture in the directions. I was wondering if the kit has changed over the last two years and that is why the directions are different from the kit we have. Please let me know what I can do to fix this.

2016 was a long time ago. Since then the GoPiGo3 has been released which is different.

Do these instructions work?
