I just bought a new trunklid for my car. since it is a ProTouring car I wanted a cooler looking rearwing and I ordered a TransAm wing.
I want to save my present trunklid so I also bought a new repro from OER.
Now to the interesting part for thsi subject.
My Z/28 trunklid, car is a 05C, has the holes in the bracing for the Trans Am Spoiler, the OER trunklid don't.
My Z/28 trunklid has the two sets of holes for the emblem.
Original lid with TransAm spoiler holes in bracing
Repro lid without TransAM holes.
