I'm wanting to get rid of the tailgate handle (pole) but keep the step on my truck but I have found 2 different part #'s and am confused. I have a 2012 King Ranch with 6 3/4 foot box. Below are the part #'s and descriptions. What are they meaning by box extender? The plastic thing that folds out and down on the tailgate? I don't have one and don't plan on adding one. Any help is appreciated.
Part #YL3Z9943121AA - Access cover 6 3/4 FOOT BOX, w/o box extender
