Rhino safe clamp

After a lovely day at the safari park with the kids yesterday, I got home to find that, as we’d swapped vehicles so the kids and I had more space, the Mrs has kindly gone under something she shouldn’t have and bent the bars on my safe clamps. I’m having a look around online but so far coming up short, does anyone know if you can buy just the bar for them rather than replacing the whole unit? Failing that I’m probably looking at rip-offs from Ali-express and using my existing clamp arm.
