There are some really cool features of the '68 Cudas compared to the '67s. First, the '68s came with redline tires. Also, the hood inserts say "340-S". Finally, if you look carefully at the rear of the rocker panel, just in front of the rear wheels, there is about a 1 inch raised section of the rocker that is sort of serrated. I think this is meant to evoke the barracuda "gills" like the chrome rockers on a real-life '70 Cuda. These are all the colors available for '68 Barracudas.
