What does your fender tag say? My A66 Challengers had the J54 sport hood code right on the tag as well as the buildsheet. My convertible was loaded but had the standard gauge package (with the optional clock) and a manual windshield washer pump. It also had console with slpastick, PDB, PS, 15" ralleys, bumper guards, side moldings, PW, PT, am/fm 3 speaker stereo, A01 light package, A62 6 way seat, and a rim blow SW. Great first car which I paid $400 for back in 1978
