I have two questions one is which adhesive should I use to keep the charge port down. Then where can I get replacement screws? There are 2 screws on the bottom of the computer near the charge port. Both I’m assuming had little plastic rings and a gold nut. I have both gold pieces but I don’t know where to get the plastic pieces.

hot glue work wonders on damages screw threads and holding things in place after frame damage. as far as missing screws or components, a quick google search with your model number and replacement whatever youre looking for will get you what you need.
