Nit sure what Tony means by a different design. There’s a place on all the NBS fuse boxes where the fan relay/ fuse box slides on and clicks into place. There’s little protrusions on one and grooves in the other. If yours doesn’t have those you can screw or rivet it in place. I just went out and took this pic on my 02. It’s a clean, factory look. Mine slid in place. It’s the triangle under the fender mount. And you don’t need to worry about replacing fuses. They don’t blow. Aftermarket is another thing- those will. The top pops off for access.
