I can't do that, Jim. If I used Super glue then I'm sure the "dot" would stick both me and the seal together.
Then, if I tried to get them apart, another finger would get stuck to the first (usually, but not always, from the same hand) and then as I pressed the seal in place those two fingers (and the seal) would get stuck to the body or trim ring or both.
No, with Super Glue, it's best to let sleeping seals lie.....
@bt The "hat" of the "T" goes flat against the body, and the inside of the "T" trunk fits up against the trim ring. Put the headlight bucket onto the hanging tab at the top but only install the screw at the bottom finger tight for now.
Start the seal at the top, pulling it around both left and right sides equally while moving the bottom screw tab closer to the body. Once you get things mostly together, you can do a final tightening of the screw.
While you do this you can adjust the seal by pulling it here and there to get it even all around. It takes a couple of tries to get it right (more, if you're OCD like me) but it should fit around and look sharp.
You may have to adjust the top tab on the body to get it to fit right at the top. Bend the upright part of the tab in or out to get a good fit at the top and then work your way around to the bottom equally on both sides.
