Where to find a replacement Spindle/Take-Up Reel/Pin to repair my Denon DRR-M30? *Pictures

Long story short, one of the Spindle/Take-Up Reel/Pins (I am not sure of the technical term, please see pictures) has cracked and only intermittently turns the cassette. So sometimes it works, sometimes it doesn't.

My unit is a Denon DRR-M30.

I would like to replace this one piece, however, I am not sure what part I need to look for.
Can anyone help me find this part so I can fully restore this cassette deck?

Thanks!
