Help finding a nos passenger side mirror?

Hi guys, been looking on these forums on and off, just decided to make an account. I have a question... Were there any passenger side mirrors manufactured in the style of the one to match the one in my pic? I have a 1973 Dart Custom, its my first car, it doesn't have a passenger side mirror and I'm blind in my left eye sooo to be able to legally drive it with my condition, it would have to have a passenger mirror. Plus, it'd help me feel more comfortable if it had one as well. I'm wondering if anyone can tell me if they were produced back then? And if so, where could I go to find one? Ive seen some eBay listings but... $250+ for a (probably) cheap chinese reproduction? I mean if thats my only option then okay, but my cars all original I do believe (with the exception of tires) so I'd like to find an original mirror if one exists... Any help is appreciated, thank you in advance..
