I'm putting my bumper back on and the fitment is really off. The gaps are huge... What screws should I put back in first when I install my oem bumper back on?

 

The tabs on top of the bumper where the headlamps are should just snap back in. Try to line the bumper close to the headlamps as possible and put the two screws in the corner first to help hold it in place.

 

Thx ^^^ but I still don't get why both ends of the bumper will not perfecly fit anymore. It's on top next to the wheels..

 

its got to snap back in and clear all the linings. same with the bottom. you have to make sure all the linings go back where they were. might need two people...but i've always done it alone.

I've taken my bumper off numerous times without any problems.

 

If you haven't tried it, start from the center and work your way outwards. Like Kinda line up the holes on top of the grill first, then the headlamp area, then the top corner of the bumper. And do what sinister said about lining up the liners.
