Where do I find tail light lenses?

My 75 cj is in desperate need of tail light lenses. The housings are good. Just need the lenses. I cant seem to find anything that will work. Thanks.

 

I have two used intact ones, different styles. One says 76, the other 75....one is larger in diameter than the other.
