These original clips hold better than the reproductions we offer. If you look closely you will see the angle bend is more acute on the originals. For you 71-73 owners with warped panels you will want to use these original clips (at least along the bottom edge) for a tighter hold. The only difference between this spring clip and the other used one we offer is the presence of the foam spacer pad.
Helpful tip: Door panel clips install sliding toward the rear of the vehicle.
