Chosen Solution

Hello fellow fixers, After a fall on hard surface the right bumper was stuck in the pressed position and there was rattling inside.I opened the deck, repaired the bumper as far as I could and am now waiting for the replacement to arrive.I found the little bits that were broken off and rattling but cant identify where they came from as nothing is obviously missing.

They are obviously identical and mirrored but I couldn’t find a spot where they go. Any ideas?Thanks!

@spacemarinov, Those are plastic clips / retainers, but it’s almost impossible to tell exactly where they broke off without having the part(s) in front of me, to inspect.
