Yes, it is the 72-74 Rallye fender louver. It is 2 parts; pot metal with a plastic insert. The insert goes behind the pot metal louver and is a black plastic. They break easily and I don't know if they are being reproduced. The louvers get bent if the car goes through car wash brushes due to the fact Chrysler did not think to put the mounting studs on the tips of the louvers. I will keep my eye out for one and let you know if I have one.
Thanks.
