Question: C6 Front Facias/bumper cover

[Luiparra]

Are there any minor or slight differences between years for the front facias of Base C6 Corvettes? I know very well the ZO6 and Grand Sport models have air scoops and lower lips/effects which the Base models don't have. I ask this because I keep noticing that my 2008 has a slight drooping at lower opening/grill compared to other Base Corvettes which I don't see this droop effect. Is mine missing something internally (hardware or bar) that produces the "droop" effect if missing? I been thinking of taking it to a Chevrolet Body shop and have it looked at, but want to hear some opinions or facts from you guys and members before I take the time to do it.
I bought this Vette used and had it inspected in addition the CAR FAX came out clean. I did notice a minor paint overspray in the black plastic egg crate grill which grill is practically invisible to the eye unless you bend down and look. I was even thinking of replacing this egg crate grill with a horizontal grid type that Corvette after-market stores sell. However I am reluctant because the lines to the lower side of the facia cover wont be parallel to the grill and will probably make it look worst.

Any info I can hear or take action? Thank you ! :confused
