You are buying ten (10) NORS Auveco fasteners. They are general purpose (universal) moulding clips with mastic sealer nuts that are used on various models and years of Buick, Cadillac, Chevrolet, Oldsmobile, Pontiac and GMC that have 3/4" to 1" wide mouldings. They are not for any specific application but they are a nice replacement for the original clips. The clips have a 1.312" long x .545" wide plate with a 10-24 threaded stud that is .545" long. These clips have a foam sealer. The mastic sealer nuts have a 3/8" hex and a 1/2" flange diameter. The nuts are NOT old stock.
