NDA1402 Missing Ice Maker Auger/Ice Bin

We recently purchased a class A with an ice maker in the fridge which is model NDA1402. The ice maker works but is missing the ice auger/bin and Dometic said the part is obsolete. They did give me a part number of 3313470.085 but when I search that, nothing comes up. I have stumbled across a photo here of the piece I'm pretty sure we need. Any help is greatly appreciated.

Thank you,
Jodie
