Whether you need it depends on the year. Some years had an issue with the holes not being deep enough in the block on the passenger side, so that the bracket bolts were torqued against the bottom of the hole and not against the bracket. That leads to vibration, metal fatigue and eventual failure of the bolt and/or bracket, causing the engine to suddenly tilt so that the fan encounters the radiator.

I don't recall which years were affected, so you might want to search for that info. I just went ahead and replaced my brackets anyway as part of the overall bulletproofing strategy regardless of whether I really needed them or not. Remember that Brown Dog gives a 10% discount to forum members, so that's like a $30-$35 savings on the full kit.
