Listed is a brand new, still in the plastic sleeve running board that fits on the left side (driver side) 2007-2014 Chevrolet GMC Crew Cab 1500, 2500, 3500..  This piece is the standard GM 20990095 running board.  This is the 6" oval and is 85" in length.  If you google the GM number, you will see that a pair runs from 500-800 dollars.  This is only 1 piece.

Great replacement for that used, dented, scratched running board.  I am posting this for a friend.  You can contact him at the number listed.
