E*Thirteen Lockring replacement, what else works?

So i fell with my bike and broke my Chainring and bent the ring lock.

this is the chainring I am getting: https://www.ethirteen.com/collections/all-cranks/products/helix-r-guidering-direct-mount , gonna get the 30T, same as I had.

These are the cranks that I have: https://www.ethirteen.com/collections/all-cranks/products/helix-cranks

I am unable to find the lockring though. i see they have it https://ethirteen.eu/products/direct-mount-chainline-spacers-and-lockring but they want 30 euro in shipping for that which is crazy. are there any other lockrings that work with E*thirteen?

I have everything but that ringlock is the only thing that seems to be very difficult to get and would need to get a replacement somewhere else.
