Early vs Late 99

Forget about the door sticker, just look for the AIH in the spider as seen in this pic. This pic shows a AIH delete plug with a boost fitting in it but either way, if you have this on the truck it is a late 99. Also as seen in the picture where the word HPO Line is, on an early 99, this part of the spider will be smaller/tapered down towards the turbo.
