Missing panel by refrigerator

I'm in the process of restoring my '67 Overlander. The interior is original and complete except I am missing the refrigerator and the cabinet panel next to the fridge by the door. The panel I'm talking about is the top left picture of this beautifully restored Overlander.



Does anyone know where I can find a panel like this?



Does anyone have a pattern that I can use to make one?



Thank you!
