Lens hood replacement recs sigma sport 140-600mm

Hello! I was just reaching out to this sub to see if anyone had any recommendations. I currently have a Sigma Sport 150-600mm lens. Shortly after purchasing the lens, the pin to secure the hood broke, and I have been shooting sans hood since. I have tried to replace the hood multiple times, but every one I order (all advertised as fitting) is just a hair too small for the camera.

I really do not want to spend over $100 for just the lens hood especially since it breaks so easily (same happened to my friend with the same lens). Has anyone else had this issue? Did you replace with a sigma branded hood or did you find a good knockoff? TYIA!
