Hey I was wondering what do I have to do to get the Iroc style into my 1986 berlinetta the front bumper looks as tho its completely different but if I'm not mistaken cant I just stick the side skirts and door flares right on figuratively speeking thx for the help

 

You would need an actual iroc/rs/z28 bumper that has the holes to attach the ground effect on the front bumper, and the same for the rear bumper. The door fillers and ground effects will have to be drilled in and then bolted on. Its not that hard but it takes a bit of know how and a lot of time.
