I don't know, if there is a source for reproduction printed underhood stickers. There are a buttload of different calibration stickers, as far as exactly matching what your truck should have.
I haven't actually had to do this (yet!), but for the older trucks there is a Ford book that should show your emissions sticker. It's called the "Car & Truck Engine/Emission Special Specifications Book", and I would assume that one exists for the 2000 models.
Example. I have a 1994 Explorer. This is my truck's sticker:
Note the " K Y Z " code in the lower left corner.
This is the factory book:
And this is the page for that calibration code, which has an image of the sticker itself:
If you had this book for your year model, or a good JPEG image file, you should be able to find a printer that can use the image to print you a sticker (hell, there may be home printers that could do this; I'm hopelessly behind on all of this modern high technology stuff). You would want to get it printed on a good self-adhesive vinyl stock.
Off the top of my head, I'm not sure about the belt routing sticker. That may be easier to find from a vendor as a pre-printed reproduction sticker, or even as NOS (New Old Stock); there are less versions of that sticker versus the calibration sticker.
I like seeing people restoring these older trucks; Good Luck!
