My rear valance panel has never looked quite right and finally investigated. Looks like bolts for bumper guards should go through valance panel and into panel bracket. My bumper guard bolts have speed nuts inside panel but no bolts from bottom of panel to bracket. Panel has always looked like it is not tucked up under enough. Valance panel mounting kit for a 67 only has small screws but bumper guards mounting kit looks like it has bolts and nuts that would solve the problem. Anyone have a 67 coupe that could take a look and advise?
