1973 Winnebago Assist Handle Plastic

[Dragonfire]

Hi All,

Hoping that someone can help out a friend of mine with a restoration. Looking for drawings and dimensions for a specific part so I can 3d print it for him. It is listed as this in the manuals - 031564-03-000 Handle - Assist - Recessed. I have attached pictures, it is the plastic behind the handle. As you can see it fell apart when he removed it. Hopefully someone has one in good condition they can send me drawings and dimensions of?

Thank you!
