That looks like a hook you can buy at Home Depot or any hardware store.
Otto makes a good point on the hook. Might have to re-form or open up the hook end, but that's a good place to start and should make it easier to do a fab.
If you need the "spring" the part number 368244 (info provided by Dan) is available from Dan's Obsolete Gm Parts in Chinook Mt, call 406-357-2615. Record shows he has 11 in stock. I've done business with him several times. Good people.
Best wishes.
