I'm not sure about the handle as I'm at work right now. But of the 2 I stripped, 1 was from the bottom of the tailgate (it is facing the ground when tailgate is up, and facing bed when tailgate is down) and the other is on the bottom of the sides that holds tailgate to bed.
I would really appreciate if you had some non-stripped!!
Ahh, nope I don't have those. The handle is held to the tailgate with three bolts, most of these I have seen are torx head. I have seen a few gates that had hex head bolts here though...
Good Luck!
