'93 Caravan corner light lens

I've been trying to buy a new clear lens for the right front cornering light - but none of the online parts stores even list such a part. They all list & have photo of the headlight lens replacement assembly which includes the long skinny amber lens, but none of the pictured assemblies shows the cornering lens. I have to replace the cornering lens to pass state inspection. How do I get one? Am I missing something?
Thanks, Space Cowboy
