Wondering where is closest junk yard

thats looks like what I want but what are thos elittle hooks in the back with the red circles.
Cant I just use ANY single din cup holder?

I also need one where the cup doesnt go INTO the cup holder but stays on top of it. So not just a hole with a ring but one with a bottom layer as well so the cup stays mostly ABOVE the cup holder not halfway through. The shift knob still too close otherwise.
