There is a plastic half lens under the chrome end cap. The 68 chrome end/ grille extension thing is blocked off by on the headlight side and only permits the cornering lamp to shine light towards, well, the corner you're going around.
I prefer the 68 grille as I find the chrome ribs compliment the taillight treatment. The front bumper harkens back to the 60 Imperial with the pronounced brows, and the wider side profile with the marker lights carries the side body profile to the front of the car, which I also like.
I do wish the wood had continued in 68 on the interiors...the bronze pieces are almost always missing (I only have a couple of pieces and will need to figure something out).
I could go on, but I'll summarize that I feel about the 67/68 Imperials in much the same way as I do about the 59/60...I like certain aspects of each but would love to have either. I'm lucky I could find and save this one.
By the way, still looking for an Electroeye for my headlight sentinel system and Auto pilot linkage from the Autopilot servo down to the accelerator/ trans.
