Kenny 71 GS grille does not have any chrome bars, it's all plastic. Here is a photo of my original 71 GS grille. George
Actually I do have another original and a repro 71 GS grilles. The repro 71 GS grille are very well made and it included the grille mounting studs.
I have a grille that needs repaired, but the car is going to be too nice for a patched together grille. What do you need for each of those grilles?
