A ground anchor bracket for supporting at least one wall brace at an earth anchor includes a sleeve that has a wall structure surrounding a hollow interior that is configured to receive a stem of the earth anchor. A platform is coupled with an upper portion of the sleeve and has an upper surface that is configured to support a shoe of a wall brace. A post is coupled with the platform and the post protrudes upward from the upper surface of the platform so as to be configured to engage a slot in the shoe of the wall brace. The upper surface of the platform may be substantially planar to simulate a slab floor surface for engaging the shoe of the wall brace.
