Part inquiry/trunk

So I was loading a bass amp in my trunk and I broke a metal bar that supports the trunk, but I have no idea what the part's called. I was wondering if anyone could help out.

I have an 03 cavalier.

If you mean the spring/torsion bar that holds it open/helps lift it, just ask for "the spring that holds the trunk open". Anyone should know what you mean by that.

Thanks man. I've been having issues with trying to translate what the fuck it did for some reason lol
