Missing bolts/fasteners (2013 CX-5)

[speedy8727]

While washing my old 2013, I saw that I am missing a bolt (both sides, rear). See image below. Someone can show me what piece I should get? If there is rust in the whole, maybe I need another solution (just bolt and nut)?

If the hole takes a screw/bolt, rather than a plastic rivet, take one of the other bolts out and see if it fits the hole. If so, then obtain a matching one from a hardware store.
