Is there a question in there?

Now you can just buy the entire dealer service manual set with everything for really cheap.
Here is the set of 4 for $70,
1999 Chevrolet GMC Dealer Service Manual CK Truck Silverado Sierra Early Edition | eBay

Or the PDF version for $10-$15 (that you can always search and find on that big auction site).
Chevrolet Silverado 1998-2006 Service Shop Repair Manual USB | eBay


Also, not everyone might be aware of this, but 99 was a split year for pickups. There are 99 OBS and NBS pickups. The 4.3 was in an NBS, but if anyone is searching and finds this...

I was just giving you an example on the manual. They are pretty easy to find.

Are you trying to find a mounting point, trying to find the ground schematics, are you just posting it so other people know? You didn't really give a reason for the thread, as in, is there a question you are trying to answer?

99 was a split year for the pickups. They made obs/gmt400 and nbs/gmt800 pickups that year. The gmt400 wasn't called a Silverado or Sierra, but that wasn't directed at you (it was in case someone finds this while searching for their 99). 2000, was a split year for the SUVs, GMT400/OBS and GMT800/NBS.
