I'm having a heck of a time getting the front bumper back into place. I know to start around the tabs below the headlights, but I just can't get the one side of the bumper to snap into those tabs -- especially the far side toward the center of the car. Any hints? I finally locked the one side's tabs into place but the other side just won't go. Any advice?
Thanks.

Update: I ended up shaving down the tab below headlight with a fresh blade, then used a very thin metal tool to get the female bumper piece over the tab and locked into place.
