replacing headlight unit

[rolling_project]

Hi all,

so I just went out to begin replacing the headlight with a plastic one I have acquired, only to find that it seems more tricky than I thought it might be. Can anyone describe, or point me towards an article that describes, step by step removal and refitting of the headlight assembly? There seem to be 3 bolts which I can't begin to think how I will access them at the end toward the grill. Do I need to remove the grill (seems I do) and if so, how do I do that? I have found the fastenings at the top, but it appears to be bolted to the headlights at the base and again, I have no idea how to access this bolt!

HELP!

I must ask before I bend and snap something and then have to source more hard to find parts!!!

Thanks for all help!
John
