Can you remove the part of the brush guard that covers just the headlights? I see that there are ***** in the center for adjustment, but at other side, it looks like it is bolted to the rest of the brush guard making it unable to be removed.

If I wanted to change my headlights on my 2000 disco, I would have to take off the whole wrap around brush guard?

 

You are talking about the "grill" over the headlight lens? They came off on mine. I didnt want them so I took them off and they are in my garage waiting to be sold.
If you are replacing your light bulb that comes out through the back under the hood.

 

On mine, those knobsbolt that part in place. Unscrew and remove. The part that looks like a bolt is actually a nub that holds the piece in place.
