Thanks! The bumper must be removed to fit the bracket for the front mounts of the unit. I have attached a pic here of the bracket highlighted. Next to the bracket (on the left side) is the alternator air duct. The brake ducts for both sides must also be removed and replaced after install of the mounting brackets.
The factory under ride protection- a small bar that runs across the underside of the radiator- will be removed. This unit uses the same bolts on the body to mount. They are not long enough to clear both brackets. Our instructions said nothing about this.
Here's a tip: Mount the units front tabs BEHIND (to the rear of the car) the newly installed front brackets. If you mount it in front, the rear mounts will be looking for that 1/4" of clearance to mate properly.
Here's a pic of the parts- including the brackets:
