Please help me identify this

Hi. I need help identifying this part. I have a left and right both and it's very heavy and has really nice chrome. I got a lot of car parts from an estate auction and many were MG, Austin Healey, mustang, and Camaro parts. I have been able to figure most of them out but there are a few that I don't have a clue about. There are no markings anywhere on this. Thanks for any help you can give.
