You are going to want all that stuff in there along with your tie rod and drag link or at least a broomstick on your knuckles, etc so you know where it will be to match the angle/oscillation with the track bar. You also want to be careful on how tall it is otherwise it might get stuffed into the frame. I think mine is ~ 6". You could go large and then cut it down if you need to weld it on now, just dont drill the hole yet for the bolt/stud.
