There has also been a few questions about putting things under the fenders. Again, some old build pictures may help answer some of those questions.
Pic 1) this is when I was building the inner fenders. This is the passenger side with the inner part of the inner fender bolted to the truck. The completed version had those inner fenders extended outward, and was level with the arch of the inner fender to cover the tires and connect to the outer fender sheet metal.

For reference, the bottom edge of the small square piece in front of the door is the level of the top of the fender. The front nose panel is bolted in place at its current position. The top curve of the fender runs in a straight line from the bottom of the small square to the top of the nose panel. About even with the front of the tire you can see the bracket bolted to the inner fender. That bracket holds the 4" diameter plastic carbon canister that is still present on the truck. The carbon canister is about 8" long, and the bracket captures the center of the canister. The area where the inner fender curves forward and is bolted to the nose panel is the only unoccupied area under the fender, as you can imagine, getting into that area is not simple.

Pic 2) this is the driver side inner fender. The angle iron here is holding the nose panel in position and the rear is clamped to the fender mount. If that rear clamp was up 2" higher, so the bottom was under the square piece in front of the door, the top of the curved edge of the outer fender would be under the flat part of the angle. For reference, that piece of tubing that is clamped between the angle and the inner fender is 1 1/2" high.

Pic 3) This is with the outer fender bolted in place. notice how congested everything is? The ball looking thing is the cruise control servo. What you can't see is that towards the front of the servo, tucked under the fender is the ECM and its associated wiring and behind the rear of the servo is the heater fan relay, also tucked under the fender.

The last post already showed the driver side fender.
