They were originally held with metal clips along a series of holes in the body. The shorter strips around the cab corners and such had studs that you bolted from the inside of the cab. But if you order new ones from say LMC they now come with adhesive backed clips. Or you can order the adhesive clips alone and use with the original moldings if you have them.
