Port light screens

[womble]

I have a 1993 C30. The opening port light lenses measure 12 x 5 inches.
Does anyone know of a source for screens of this size?
One port light does have a screen so they do/did exist.
There is nothing matching on Catalina Direct.

Wonder if the Gray 5x12 screens would fit? They're for sale here.
