make sure if you get the panel clips from a nissan that you didnt drill the hole already for the clips that are supposed to be used cuz the nissan are a hair smaller . i made that mistake then had to buy then 4 3 bucks a piece at mitsu . The way i installed them was by putting silicone on the end of all the clips then pushed the skirt into the body then pull off and you will have the marks for all the holes . Make sure you make the holes a tad smaller . i also had that problem. Then on the bottom just use self tapping screws with washers .
