The truck was all original when I got it. The clips were on the seat frame holding the wrap. The hog rings were only used on the corners to hold the extra material together under the seat. The seat material was a lot thinner than the replacement which is why I am probably having trouble with the clips.

Here are the pictures of my original seat with clips before I took the cover off.
