I'm not sure if i want to screw with the panel. I'm going to get the cap back out of the sealed box in the morning and take one more look at things. I know i can get the lid screwed into place with it being slightly cocked because i did that. But i was quite aways from the trim ring when it was tightened all the way down. It would look stupid without the trim ring. I actually thought about using some kind of bonding adhesive to hold the trim ring against the fender (glue, lol) but i'd still have too much base showing as well as screw heads
