These are what I will be using for headlights. They will be mounted to resemble the concept car's headlights and due to their small size, they won't have to be recessed very far.
They are found on 93-9? Olds Cutlass Supreme 2 doors.
I think they will look good as the 4 headlights and 2 clear lensed turn signals closely resemble the concept's 6 light system.

The header panel for these is fiberglass which will make it easier to work with. the 2 sides will be separated and most of the protruding tabs will be cut off.

The light arrangement is also stepped so it will work well with the angle of the front end.
