To install the lower trim: READ THIS THROUGH SEVERAL TIMES BEFORE DOING IT.
Install the special clip in the corner stainless like this. Crimp the bottom inside where the notch it.
Put screws in the upper trim loosely enough to hold it down, but not enough to prevent the corner trim to slip over them. Install the screw in the retainer clip after they are installed. Slide them up and over the end of the upper trim.
Install the stud and nut clip into the end of the lower windshield trim and move it to the appx location when installed. Install the screw in clip
on the body. Now slide the lower inside side end over the screwed in clip and push it toward the center enough to get the outer end to
fit into the corner clip, and also make sure the stud of the installed stud clip doesn't scratch the paint. Make sure it gets put into the hole in the body.
Adjust the stainless so it lays flat. Do the same on the other lower pcs. The last will be the center clips. The one in the middle that goes under the stainless is just slid in one end enough to clear the hole. Use a pick to move the clip so it is inserted in both lower stainless pcs and install the screw to hold it down. The stainless clip is started over the top edge, and snapped down over the lower. Use the width of this clip to gauge the location of the 2 lower pcs, before you install it. Now find the 2 studs on the lower windshield clips under the dash and install a nut and washer with plenty of strip caulk around the stud, also apply more after the nut is tight because this is a place water will try and run into the car. You can also put some on the stud and back of the clip before the stud is installed in the hole.
