Yep. Hinge to body bolts give you left/right adjustment and in/out of the bottom of the tailgate.
Hinge to tailgate bolts give you left/right tilt and up/down. Maybe some left/right movement also.
The pic looks like you need to loosen the hinge to body bolts and shift the whole shebang to the left. You have to loosen the bolts that clamp the springs tool.
