Where do this rubber fittings go?

I'm re-assembling my macbbok Pro A1708 after a long wait to get my screen replacement and during the re-assemply process I found this two rubber fittings.

I thought they might fit in some vent or even in the USB C ports but I really don't know and decided to askbefore I do something wrong. Any ideas? There's only two of them which fit my USB C port theory ( 2 port model)

Thanks in advance for your help guys!

These are the rubber gaskets that help prevent water, dirt, dust, etc. from getting into your USB-C ports. These most likely fell out whilst removing/moving your logic board and should be replaced and resealed immediately.
I recommend taking your time and following an in-depth repair guide video for your display replacement to ensure they are installed properly and that you did not miss anything else.

Just ask if there is anything else!

@cpevv - The iFixit guide MacBook Pro 13" Function Keys 2017 Display Assembly Replacement doesn't require taking out the logic board to replace the display assembly and I've never needed to either.

So while they look like the gaskets they normally stay on the connectors when you pull the logic board.
