OK this is kind of a dumb question but I just can't get a strait answer. My truck is a 1999 4x4 with all the option except leather and I was wanting to know why it doesn't have the little black plastic air dam on the bottom of the front bumper? All it has is a black rubber flap that I tuck up into the front bumper. Could someone tell me what is up with this, I'm totaly lost.
Thanks
