Carburetor Spring Application

[69VN]

Could anyone tell me what the correct application for this original carburetor spring is for? It was removed from my '69 Camaro years ago but I can almost bet it's NOT the one that came from the factory on the SS350. I dunno, maybe I'm wrong but that's why I'm posting this help ad. Thanks for your help guys!

Spring measures 6 7/8" long and the coil diameter is 3/8". Anyone ever see a return spring like this? Trying to find out it's application.

Thanks,
