'69 Dart Tail Light Component Needed

[ocdart]

I'm looking for the red plastic dividers that separate the tail light bulbs from the backup light bulb in '69 Dart tail light assemblies.
Van's Auto sells them but only with the tail light housings. I called them today and they won't sell them separately. Not logical because they're certainly not manufactured by the same people that manufacture the cast metal housings.
Tell me what you've got and maybe we can make a deal.

Thanks!
