AAR Cuda's and T\A Challengers have the Hemi fenders but no tag on the inner fender to designate them as such, unless the Trans Am tag serves a similar purpose. I had to get the Hemi fenders for mine when I replaced them back in 81. Got both of them from Chrysler to the tune of about $250 apeice. The full quarters for my pace car were cheaper when I got them from GM 2 years later.
Picture of it when it sold about a year and half ago by the second owner after me.
