I've never done the drip rail strips but they do clip on. Very easy to damage them so hopefully there will be someone along to give a few tips. The side trim clips have to be slid into the back of the trim and positioned accordingly. There is a cut away that allows them to be inserted. VERY easy to damage your paint, especially around the holes in the body. As you line up the clips, put a lump of Dum-Dum or similar non set caulk, around the clip before you press it home. This keeps the water from seeping in. Not critical on the front wings but essential on the rear ones. You can add some more sealant around the clips in the trunk. The door ones obviously need the cards off but do them if you can.

The proper side trim clips can be hard to find. When removed they are usually rusty, so not really worth using again. If you know of a 4 door Amazon lying around, pull off the trim that runs down the inner side of the B posts. These trims are held in place by the same clips. Used here they stay rust free.
