Personally, I never liked those covers with the round holes in them.
Here is a pic of my first '68 the day I brought it home in '82. Unmolested except for the pushed in front bumper/hood, faded paint and that goofy door ding strip.
Wheel discs and tires got swapped for Rally IIs and white letters in short order. Bumper took a couple of months....Never did get the faded paint re-done. Unusual that it had headrests and a rally stripe.
