I spoke to the guys at ok 4wd and they said they just remove the inner gasket which is what you mentioned so that's what I will do. The place where I had it installed had never done one of these so they weren't sure and did not remove it. Thanks again for the info and good luck with your truck.
Thanks for your reply. Are you able to close the hatch when the tailgate is already closed? That bump prevents me from doing that. I had it installed by a local company. Not sure if they removed the inner rubber gasket that goes over the horn on the tailgate. I will find out. Thanks again!
I ran into a problem with the back hatch not closing because of the bump on top of the tailgate. Did you have that issue? Might be I need shims changed. Could you tell me how many shims you used in front, middle and back? Thanks! Your truck looks great!
