According to your valve cover sticker, your truck did not have a cat. The attached photo shows two different stickers for 1999 models. The lower (black) sticker has "OC" listed....which means it came with a catalytic converter.

If your truck is a 1999 model, then perhaps you can print out this photo and show to your emissions inspector.
Hope this helps...
