looking back through some of your earlier photos - this game has gone through a batch of post adjustment - or rather move the post because the timber has been flogged out in the original locations.
you didn't have a close up but the post behind the targets closest to the ramp, but it looks like it has been moved. It that is the case, secure the plate to the 3 other mount points and relocate the lower post near the ramp. The mount plate should be flush and parallel with the SS rail that leads up to the scoop.
also the post near ramp needs to have one of those white post sleeves to support the old plastic or this SS plate.
