If I understand your question correctly, the "whiskers" are mounted with the soft part up and the metal part down. They attach with clips that have sharp barbs that extend out-5 per door I think. The clip is mounted to a thin metal edge of the door, and the soft metal part of the "whiskers" (bottom part) is gently tapped into the clip. The barbs grab the soft metal and secure the strip to the door. Use a small strip of wood and place that strip of wood across the whiskers and tap on the wood. In this way, you are spreading the load of each tap of the mallet across the piece so that you don't dent the strip in one place. Otherwise you will get a ripple type of effect. You have one chance to get this right-if you mess up, you will either need to live with the ugly mess or buy more strips.
Here is a picture. The whiskers go on the inside track of the clip between the window and the door. The outside track of the clip is used for the chrome strip on the door.
What confuses me about your question is that the soft part of this strip is exposed when installed so that if you had an example to look at, you would know that the soft part of the strip faces up. You must have been missing this piece from both doors and thus don't have a reference point. Hope this helps-if I mis-read your question, then igonore my ramblings.
Best,
Tom
