I am trying to get the front end back together on a 72 Challenger Rallye, I have the Dave Wise book and the exploded views of the grille pieces. There is no clear picture of the plastic valence or what it is attached with in either publication. The Wise book leads you to believe that valence plastic insert goes in with 1/4" bolts and U-nuts. There was one old broken bolt/nut still on the air shield, I believe it to be original. It is definitely smaller than 1/4" and looks more like a J nut? I bought the Grille Hardware Kit AMD and nothing in it fits for the plastic valence. Attached is the valence I am trying to attach. Any help greatly appreciated!
