A 5th silver aluminum wheel that matches the four that came with the truck so I could legitimately do a 5-wheel rotation without looking like one of "those" trucks.
I already have your billet . 44 mag shift knob and love it, except in the winter time. But I would be game for a billet valve cover or the door sill plates.
I have this for my truck. Bought it off a member who put on aftermarket wheels.
Check Ebay - it's pretty easy to find someone selling take-off factory wheels.
Or, buy one from the dealer. They run under $1k each last I checked.
[Also, the aluminum wheels are forged, not machined from a big hunk of aluminum. I don't think you'd want to hog out a wheel from a giant ingot of aluminum. ]

I would go for the billet door handle if they were black.
Aluminum wheel center caps to replace the factory plastic ones.
I've always thought the grille and grille surround would be much nicer made from polished aluminum instead of plastic. (Impractical to hog that out of a block of aluminum, though).
Aluminum headlight and heater control knobs would be cool.

If you could make these giant hitch balls and sell them for $100 or less I'd take a bunch.
