Male Matty wand V-Hook size

I’m making a male v-hook for a friend to use to attach their Matty Thrower to their pack.

I understand it is slightly narrower than the movie accurate v-hook, unfortunately I don’t have access to the thrower to check I’ve shaved enough off.

If you have either bought a compatible one or made one from scratch, please could you tell me the width of the top and bottom.

Thank you

Gordon
