Excellent, excellent work!
Sound: exterior rattle
Cause: hood hinge bolt slightly loose
Fix: tighten hinge bolt
Further notes: this rattle can be difficult to trace. You will hear it at low speeds, as in a parking-lot, etc.
I originally guessed it to be a loose front fender-liner.
A 1/4-inch drive ratchet with socket is needed. Use caution, it's tough to get a ratchet in the space available.
A slip here can scratch your hood.
Sound: chassis rattle/clunk
Cause: body-frame mount, when the weldnut on the bottom of the body breaks loose
Fix: Weld in a new nut
Pic of my right-front cab mount weldnut:

Further notes: (the rust in that pic is only an old piece of sheetmetal placed to protect my carpet)
This one is ugly.. The bolt that holds the body to the frame goes up from the bottom of the frame thru the mount,
and threads into a weldnut in the bottom of the cab body.
The weldnut though is enclosed in a "pocket" formed and welded into the sheet-metal at the cab floor.
Procedure: Locate the area over the weldnut inside the cab, pull back the carpet. Use a torch to cut open a small rectangular hole over the weldnut.
Remove the original weldnut. Place a large castle-nut (size?) in the same location, weld it in place, apply primer to prevent rust. Weld the flap that was cut from the floor to access the nut back into place. When replacing the original bolt, use anti-seize.
