Door panel arm rest

[E38flagship]

Hey guys figured I’d ask before diving in. I got a set of LCI door panels and I want to put my “arm rest portion” on the door panel. It looks like I’d have to drill out where they melted plastic “rivets” to secure them. Anyone have any good method for re securing the new ones ?

If any one ends up searching for this info, I ended up drilling out the melted plastic and using self tapping screws, it worked great ! Hope this helps someone else
