Tuffy Center Console
Full Console with Radio Comparment from Tuffy
The directions are good with ample pictures to help you figure out exactly what needs to be done. They suggest removing at least one seat, I urge you to remove the passenger seat as most of the mounting hardware is on that side. Leaving the driver seat gives you a place to sit while your getting the console into position.
After removing the stock console you need to drill out the two original mounting holes that are in the center of the storage compartment. That is the only modification you need to make to your Jeep. Tuffy provides a small mounting bracket that gets bolted to the floor just behind the shifter.
The hardest part of the installing the console is tightening the bolts that hold the two major pieces together. They screw into the shifter surround section and are left sticking out enough for the storage compartment to slide over them. The picture above shows how I supported the console with my fire extinguisher so I could access those hard to reach bolts.
