My custom (ghetto) mounting for the front upper grille area with the ZR4 shifters...
** The mounting hardware that comes with the ZR4's is pretty useless on the Camaro **
Here is what I did:
1) I used the grille mounting clamps that come attached to the ZR4's and removed them from the ZR4...
2) Took these grille mounting clamps and fastened them to the inside lip of the upper grille..
3) Used one 3" (on non headlight side) flat metal bracket and one 4" (on headlight side) flat metal bracket per shifter... I then attached one end of each flat metal bracket to the ZR4 grille mount clamps using the stock mounting clamp bolts along with a #8 nut and washer...
4) Attached the ZR4 shifter to the other end of each flat metal bracket using the supplied ZR4 mounting bolts..
Presto! Level, straight, and stealth in the upper grille area...
Now why use a 3" and a 4" you ask? My math indicated that the curvature of the grille was approximately one inch for my mounting location... Needing to keep the shifters straight (no toe in or toe out) is the reason for the different length of the brackets...
