Im sure you guys are sick of answering thisj question, but is there a web site out there that shows exactly where all the mounting points are for the ground effects?

 

what kind of car, camaro or firebird? do you need to drill all new holes or something?

 

I just put the 92 aero on my 89 camaro everything bolts up to an extent, um the rear of the rockers has a welding in bolt attached to the rocker on the 89 but the 91 92s have a tab, I just drilled through the inside of the aero and put in a skinny headed bolt to go through the rocker and into the car where the 89 did, also the front fender the will require some tweaking of the same sort, you'll have to drill or cut some slits, I had to drill some holes on the drivers side for my new rocker for some reason, dont know about fbirds
