Here's a view of mine, it sits on the outside and doesn't come up to the rear axel.
Maybe your shocks are too long. Can you adjust them?
Metal is flexible.
I lined up the header to the two exhaust studs, and adjusted it accordingly on the bracket while it sits there. Put the screw in on the bracket to hold it, when you get it where you want it, not touching the axel.
Then you torque down on the exhaust studs, and the bracket accordingly.
This is how I installed it. Did I explain clearly? Maybe I can try to word it differently if not.
Mine wanted to go behind the bracket holder, but I just bent it slightly to sit in front of the bracket.
