Hey Austin! The correct set of 5th wheel rails for a 2004 GMC Sierra 2500 are going to be the Curt Custom Fifth Wheel Installation Kit for Chevy/GMC item # C16418-204. This set of rails is industry standard which means it will work with most 5th wheel hitches on the market. The brackets are custom fit and install in pre-existing holes in your Sierra's frame.

I have linked an installation video below so you can see how to get them installed.

To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C56070. This harness puts a 7-way connector in the bed of your Sierra and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel trailer easier and more convenient.
