Teraflex HD Hinge not flush?
#11
That is a pretty small gap, variances in the hinge and door will happen. I think as long as there is no space between where the hinge makes contact with the tailgate, and the bolts are torqued to spec with no rattling you are good to go. I have one, but mine is on a boat in the Pacific ocean right now on its way back to WA, so I can't look.
