there are three tabs that swivel to hold the plate in place
they are riveted to the floor board
the two on the bottom pictured are just screwed in ,the original on the top is correct and riveted

Rivets are best but I was in a hurry to get mine on my huckster so I used screws to hold the tabs down. Problem with screws is they become loose when you use them and have to be tighten often.
