I got my iroc from a friend really cheap but it came right from a paint shop in pieces. I figured out almost everything execpt i need to know the sizr if the self-cutting thread nuts on the trim that goes on the outside of the bottoms on the driver and passanger doors i have the sizes for the rest of the kit with the execption of that. Can someone please help me out

 

on my Trans Am I believe their 11mm. you mean the rocker gfx right?

 

The ground affect the attaches to the door to make the rocker blend into the rest of the door.....11mm that is the thread size right?
