Nice driver quality E-Body mirror off a Challenger .The mirror glass is dated 12JC3 and the
part number is 35486617 with a Pentastar .$35.00 plus shipping.....other mirrors available.
I believe that since it has an integral stud on the base that it is actually a 1970-76 A-body mirror. E-body mirrors have screws that mount into nylon inserts in the door. The head may be the same as an E-body but the remote cables are different lengths as well.
