Just bought a '70 challenger with some options not on the fender tag, no buildsheet avail. Question is: are all options represtented on the fender tag, or just some with the rest on the buildsheet? Car has flip-top gas cap, wheel lip molding, tuff wheel, and power steering, none of which are coded on the fender tag. Previous owner said PS is included as a 'package' in one of the coded options (super trak-pak maybee?), I am a recovering chevy guy and this is my first MOPAR...please help!
