OK, finally got around to putting these on today. In the case of the 170-997-01-86 part, the installation wasn't as straightforward as I thought it was going to be, but in the end its pretty easy.
My problem was I thought all I needed to to was take the puck, put it in the hole in the underside of the body & close the "plunger". But when I tried that, the plunger when in with practically no resistance & the puck fell right out.
After taking a closer look at the puck, I figured out that it came apart into (at least) 3 different pieces (see the attached photos). There is the outer rubber grommet, the plastic "puck" and the plunger. If you pull the plunger out of the puck, you can then weedle the grommet off of the puck. Once I did that, the procedure seemed clear.
1. Place the rubber grommet into the hole on the underside of the body & knead it into place so the grommet fits up into the indentation in the body panel. Pay particular attention that the top "threaded" part is well situated inside the ~1" diameter hole in the center of the indentation.
2. Place the puck inside of the rubber grommet & gently make sure it's well seated such that the "legs" on the top of the puck are inside the 1" diameter hole. Before I placed the puck in the grommet, I actually pushed in the legs so that they were nearly flush with the hole in the top of the puck to make sure they all ended up in the hole. I then gave the puck a couple of light taps with a rubber mallet to make sure it was centered & seated. At this point, the puck may still seem to be a little loose inside of the grommet, but that's OK at this point.
3. While holding the puck so it remains flush and centered in the grommet, insert the plunger in the puck to the point where you feel a lot of friction/resistance. This is when I knew I was on the right track; every other way I tried to attach the puck the plunger encountered practically no resistance at all. You probably won't be able to push the plunger all the way in at this point, if so that's good.
4. Use a rubber mallet to lightly tap the plunger into place. There is limited space under the car to do this, but once you get the plunger moving it only takes a few light taps to drive it all the way in.
5. Verify that the entire assembly is secured to the body. It should be recessed a bit into the indentation & be securely attached to the body at this point.
