I had a '65 Impala; it had the wood-grain trim. A friend of mine has a '65 SS, currently undergoing a full restoration. It's a Regal Red/Black gut car like yours, but an original 396 4 speed car. He's the original owner and it has the brushed aluminum trim.
The factories often made mistakes. If it were mine, I wouldn't change it. I look at it as part of the car's history.
Beautiful car BTW.
