I have a driver side mirror for a 70-72 cutlass. Asking $125 plus shipping, I accept money order or paypal but buyer pays the 2.7%. If interested send me your zip and I can get you a shipping.

 

That looks like later g-body mirror. 70 cutlass/442 used the clamshell sport mirrors. 71-72 bullet mirror looks a lot like those mirrors but they have a shorter base with a different angle and they mount to the doors differently. The 70 style clamshell mirrors were only used on 1970 cutlass/442, 71-72 used the same mirrors as 70-82 camaro firebird and other 70-72 a-body's btw.
