upper rear shock re locator bracket

[donthekawguy]

I got my kit and the instructions are lets say less than adequate. Do I just guess where to mount the top bracket or is it a certain distance from the side rails? In the pic do I put the brackets where the arrow points or is that where the old brackets originally are? It seems to me the shocks would have to be moved out to be in the right position with a lowered truck.
