z/28 was the only car that had the two big stripes running down the hood and the trunk.
ss had the d90 sport striping often refered to as the hockey stick stripes running on the sides of the car from the base of the front bumper up through the engine # and along the top of the front fender to the door handle (see my car for an example, but it should have a gap where the 396 motor #'s are).
if a rs was a non ss or z/28 it had the d96 fender striping which were thin pinstyle stripes running on the side from the front of each wheel well (front and back) along the top of the wheel wells going straight out a few feet past the wheel opening.
you could also get the dx1 front accent striping that sort of looked like a bumble bee stripe on the front running from the sides to the hood, but instead of being one stripe, it stopped before meeting in the middle and ran down each side of the ridge in the hood stopping at about the back of the hood.
the z/28 stripes are by far the most popular these days and you see them on ss and regular cars plus all the clones.
ss hoods (ones with 2 stacks on top of hood) were only avail. on ss cars - small or big blocks, the super scoop (cowl induction) hood was an option and could be ordered on any v-8 car, but probably most remembered for the z/28. these were not avail. until dec. of '68 so if you see an early '69 or 68 or 67 the hood was put on later.
Is the z/28 better? it seems to bring a higher price. had my heart set on one when i was looking for another (i had a cortez silver rs z/28 when i was a teen), but i "settled" for a big block car with air. (no air or auto for a true z). guess it just comes down to what you like.
