* 1967 Camaro: Features a single, relatively thin, and simple molding that runs along the top edge of the fender. It's generally a more understated design.
* 1969 Camaro: Has a much more pronounced and wider molding. It's often described as a "hockey stick" shape because of its curve. It's also typically a two-piece design (though some variations exist), with a section running along the top of the fender and another curving down towards the front. The 1969 molding is a much bolder, more noticeable feature.
In short, the 1969 Camaro's fender molding is considerably larger, more sculpted, and visually more dominant than the 1967's. The difference is readily apparent upon visual comparison.
