'94 540i Grill Removal

I'm replacing the headlamps from my '94 540i. I can see that I have to remove the front grill, but I can't seem to find all the points where the grill is attached to the vehicle. Any help would be appreciated.

there's one plastic screww retainer clip in the top just above the center grill to remove. look though the front of the grill opening for the two lower release points [flat blade screwdriver with a slight twist and then tug on the grill to release those].....now for the fun part, just to the rear and outside of each headlamp unit, right up under the hood hinge/struts is a small round openning. insert a thin [12" long] screwdriver and push down 'til you see the outer edge of the outer end of the thin grill finish panel under the lamps MOVE, you've found the release for the outside edges. push down firmly while pulling forward [out] on the grill panel ends and the ENTIRE lower grill/finisher will come off the car.
