another Hello from Florida/maybe a '67 Cuda in my future
Sounds like you are refering to the 1968 Gills.. What it really is is a thin aluminum spear that runs down the body line (same as what is on my car but shorter), then the last 10 inches is a larger piece of trim which has the vertical lines you are refering to. Under the spear the rocker is painted silver.
