This is a beautiful two piece design which is meant to lay over the black plastic cowl vent area on your 97-04 C5 Corvette. The one side has the vent cutouts to match up to the factory vent cut outs found on the original black plastic cowl section.
The main portion (drivers side) laps over the other half where they join in the center. It attaches using all new stainless hardware and the same five mounting holes as the original one. Each kit comes with all the needed hardware and easy to follow instructions. Installs in minutes.
Nothing to drill. This gives the under the hood a nice finishing touch.
