LATE 1999
it all depends on the body style whether its the same or not
Yes they will as long as the 99 is not the new body style.
It should if it is the round body style such as 2001 or 2002.
4,400 to 7,000 lbs depending on body style and options.
It is highly unlikely since the body style, including the windshields, changed in 1988.
yes, as long as it has the same box syle body like an 84 silverado would have.
There isn,t a cabin air filter in yours, not used in fullsize trucks until 99 new body style. Chevy Dealer
under the hood
Yes
If the 1999 hood is the new body design then YES. If it's the old body style then no. It is hard to answer that question when I can't see the body styles. In late 1999 is when Chevy redesigned the body styles.
Not without modification as 2000 is the newer body style which was implemented in 1999.
