Yeah my truck was an early '22 model when the applique was constrained still. Definitely recommend those clamps that expand enough to go around the tailgate when its down and adhesion promoter. Could probably also get away with using some wood or something to run the distance of the tailgate to hold both sides and the backing of the applique for better adhesion. Mine is still holding up well, so I don't think you'll have any issues once its all dried. Make sure you painters tape off the paint as well so you can get a good clean seal without making a mess.
