I don't know what to order, did you have part numbers ? My dealer tells me there are no such parts.
As I understand it, there are two styrofoam blocks, LH & RH, a plate for the top of the spare, and a hold down bolt
Other people have told me this, but I can't seem to find them. The cover you were talking about is for the AWD prius
This is from an earlier post on this thread, from December, I believe. There's also a video on how to put everything in. Look at post number 12 for the video. Turns out I didn't need the protector (part number 51978-47010) or flange nuts because I don't have an AWD vehicle, but I did use the other parts.
