Liftgate (upper tailgate) does not fully latch

[mflecklr3]

I just replaced the latch and acuator on the lift gate (upper tailgate, whatever). The good news is the acuator works and the liftgate opens when you hit the switch, press the key fob, or do the manual override. The bad news is the striker doesn't fully seat. When I shut the liftgate, it doesn't sit flush w/ the tailgate and it wiggles. I adjusted the striker to the limit and it's better but not solved. Any ideas?
