Hello,

Any ideas on the best way to plaster/keep this interior trim piece down? I got this G used and it came like this. I was thinking of a really strong epoxy or an interior screw.

It looks worse and more noticeable in person, picture doesn’t do justice

 

i have the same issue, maybe try an epoxy, remember its permanent so get it right aha.
as for the left side where it protrudes out, thats normal

 

The entire cluster housing is such a bad design. Your best bet is going to be to remove it and work on it out if the car. If it’s not going good, you can buy one on eBay for cheap and just move your cluster over.

 

This is the beginning of the deterioration of the interior. You'll have to take it all apart and try to use some hard silicone to hold it together.
More than likealy it wont work. You're better of buying one in better condition just like Sobe stated.
