Had to post this, I just installed my Custom-Flow tailgate myself. cannot believe some accessories catalogs want as much as $58 to install it. It took me all of five minutes to change the tailgate over. I realize some people don't have any mechanical skills, BUT $58 to lift off one and set another in its place. I guess you have to look into some of the added costs to see if you can do it yourself.
