I just got a 68 small block car I know nothing about, I will post the tag later my question is did any camaro come with the wide chrome window strips or just the rs's my memory of them seems to think only the rs ss came with it I await your answers thanks Ben (67zl1)

The upper door and quarter chrome is part of RPO Z21, exterior style trim group. Available on any car-not just RS.

You seem to be refering to the "reveal moldings" and they were, as Kyvox stated, available as a stand alone option on any car. Your "memory" is probably refering to the 3 pc trim just above the rockers that follow the angled crease. This was part of the RS package. However, these parts are readily available and I've seen them on other, non-rs cars. Hope this helps.
