Ok, Im mounting some Z24 skirts on my 4door..I know I can do self tappers underneath, maybe some tape on the sides..and what about the rear? Where can I screw into?
You're missing the mounting point on the rear. Most likely because they were never meant to be put on a 4 door, at least the 95-02 skirts weren't.. Probably not much you can do on the rear.
Got it fixed..temporarily..
Found a random L bracket in the shed, tapped that into the bottom of my rocker panel, then tapped the bracket into the rear..it works perfect.
and it is normal for sedans to not have it.
