My passenger side mirror glass cracked on my 73 Charger. Can the glass itself be purchased or do I have to buy the entire mirror? I know you can buy the entire mirror repro but I havent been able to find the glass by itself. Thanks!

Is this what you are looking for?

Thank you sir. I have never done any business with this vendor...they have a decent reputation?

does this glass have the "objects are closer" optical effect ? if not, you may want to make a pattern [construction paper or thin cardboard-think cereal box] to your liking, then go to your local glass shop and have them cut you a mirror for around $10-15. to install, use clear silicone "adhesive".
unless you need, or prefer, a factory original.
just a suggestion.
