You can purchase sheet metal plastic plugs in assorted sizes.
Most of the holes on the Frontier are standard sizes.
I plugged quite a few holes in my floor after removing the carpeting.
I think I bought them off of Amazon but EBay sells them also.

Sweet, thanks for the info.

Why not just put the screws back in? I took off the front utilitrack and I just replaced the screws and washers after removing the track.

I did put the screws back in. The holes I referred to are not from where the bolts came out. There are four one inch diameter holes in the floor of the bed. They are under the utilitrak so you can't seem them until you take the strips out. I assume they are meant to allow water to drain water from the bed.

The holes in the bed must be an odd size. 1" plugs were too big 7/8" plugs were too small. I may have to figure out something else.
