tail light lens clear plastic

I'm looking for the clear plastic (back-up light) section on the tail light lenses of a '72 Skylark. Could've sworn I saw them reproduced somewhere but can't remember. Anyone know? I want perfect, no scratches or cracks so thinking repos unless someone has some to sell.
Thanks, Craig

 

I'll have to look at mine,as most have cracks in them,so they are disposable.Bruno

 

Hi Craig,I finally was able to go to the shed without freezing ,so I have one that has a fairly long piece missing,so you can buy this one if you still want it .It's in very good condition,so...Let me know if you still need it.Thanks,Bruno.

 

Thanks for checking Bruno. I'll PM you.
