Were pinstripes standard on 1967 Camaros?

Check out the picture in this thread:

It shows 4 1967 SS Camaros lined up. They all have pinstripes. Who did this, factory or dealer?

I've never read anyone comment on pinstripes and I think I see just as many with as without today.

The pin stripes are factory. They were included in two different options. The RS (Z22) option and the Exterior Style Trim Group option (Z21).

Thanks, I have the exterior style trim group, Z21.
