Chevelle Sport Mirrors?

[jerry67]

Could somebody help me identify a pair of sport mirrors I've had laying around my garage for about 15 years. I think they came with an old 72 Chevelle I had but I can't remember if they were on the car or just laying inside. The numbers inside the passenger mirror are 52813 RH2 9626971, on the glass are 9-DMI-6, on the base are 52812. I haven't looked inside the driver's side mirror as of yet but I'm sure it's a mate to the passenger's side.
