Can any one help me with diffuser hardware, i just got the diffuser without the hardware and I don't know where to buy and size of them.

 

For the rear mounts near the diff, those need to be custom. As for the sides that touch the bottom of the bumper, you can figure that out. Very simple. For the ones in the center near the license plate, you need to find a long bolt. Just measure. Good luck.

 

Do I need to mount the rear near the diff? Make a hole (drill)? And thanks for your help!
