Which 2001 front end are you looking for? 2wd, or Edge/4wd?
The Edge/4wd is the one with the mesh grill and domed hood.
You can purchase grills and header panels from Amazon or ebay for what I'd call a reasonable price, and with free shipping. You'd have to collect all the little parts like headlight clips.
Fenders from 1998 to 2011 are interchangeable parts, that should expand your search some.
Hoods...
If it's the flat hood they are reproduced and can be had with free shiping from same sources, but still going to cost. The same hood was used on all 1998-2000 trucks, and on all 2001-2003 coil spring 2wd trucks. Possibly a change from steel to aluminum (or the other way) but the shape is the same. That should broaden your search for hood donors.
If it's the domed 01-03 Edge/4wd hood, those are not reproduced. You'll have to hunt down a good used one.
Headlights, 01-11 can provide them. There may be some differences in bulb sockets used through the years, but you'll need to swap those out anyway for a facelift.
