Hitachi TRK-8180E: How do I fix broken cassette door/lid?

Hello!

I’m trying to fix this issue. The door/lid just falls down without resistance when I press Eject.

This is what the door looks like. I suspect a part at the bottom of the picture has snapped of as you can see remnants of glue.

I would like to see how the door of a fully functional deck looks like to try and replicate it. If you have a photo of it or any other advice it would be greatly appreciated.

This is a picture of how to remove the door from the manual:
Thanks!
