Rare sway bar? I have questions
 

I have a 1" front sway bar for a 1st-gen Camaro or Firebird. I was noticing it looks like the original color was a light turquoise. I have a set of '67 Bill Thomas traction bars in original paint that are also a light turquoise so I wondered if it might be a Bill Thomas front sway bar. The shape of the bar in the Bill Thomas catalog is pretty much the same as mine however it does not take a dip down in the middle like most every other Camaro sway bar I've seen. The ends are round like a GM bar but not exactly the same. Close but not quite. Is it possible that this is an original Pontiac sway bar for a '69 Trans-Am? They came stock with a 1" sway bar from my understanding and I was told the part number for that Firebird bar was 3958466. Anybody have any ideas? Maybe the design of the Bill Thomas bar changed over time?

Here's what the end of a 1-inch GM service part sway bar for a '69 Camaro looks like and also the end of a stock '67 Camaro sway bar.
