ok I recently got my front and rear bumpers and ground effects off of an IROC to put on my 86 berlinetta. I have the front and rear bumpers on now how should I go about putting the other pieces on.

Thanks in advance

 

You did get the brackets didn't you?

For the pieces with the studs, you need to carefully measure and transfer the measurements onto your car and drill the holes. Mount them using speed nuts from the backside.

You need to weld the rocker bracket in place on your rocker panel. You also need to drill holes for the lower front bumper brackets on the fenders. Install the front bumper first, and attach the lower gfx to it to determine location of the bracket.

Bumpers are a straight bolt on.
