Rear valance bracket reinforcements
Here are pics from the FSM of the brackets on the Cuda and Challenger. There was apparently suppose to be a total of 4 per car, 1 on each side of the openings for the bumper guards. I have 2 factory 71-74 Challenger valance pans here without the exhaust cut outs that only have 1 hole provisions per bumper guard opening to mount these. The original valance dated 3 11 70 on my 70 T/A without cut outs, as well as another 70 Challenger T/A one that is dated 10 30 69, have only 1 hole provision to mount these on each side. I have a 70 factory Barracuda valance without cut outs with a 5 29 96? date that has 4 hole provisions to mount these. My 70 AAR, without cut outs, does not have any holes to mount these but I can't quite make out the date as the elastomeric rear bumper is too close to the top edge of the pan to make it out. I also have a 71-74 Barracuda valance without exhaust cut outs that has no holes. If anyone else has documented info on use of these reinforcements, please reply, so others and the OP can figure out what they need. From what I've seen, the AAR and T/A never used these reinforcements, as the rear body panel bumper mounting cross member does not have the holes for mounting them, and neither does the 73 340 Cuda I have here.
