How to fix 79 Argosy tail light covering?

[Ms. Lala]

I am in the process of stripping and repainting my newly bought 1979 30f Argosy. I have been looking to replace what airstream suppler calls "trail light bezel brushed chrome NLA"- Basically a triple light plate cover for the rear of the trailer that is completely cracked and half missing. However they do not offer this product any more and say the part is obsolete. I can't seem to find it any where else. Any suggestions? Here is a picture of the one I want to replace

How about 3D printer? I see a new post on using one for interior parts. Take a look.

I have a 75 argosy. I replaced the original with a new tail light assembly like this. It's very similar to yours.
I ordered it online. Upgraded to led. Just can't remember from who. Hope this helps
