yep that bit, basically the whole front end
It's rivet welded in place. If you have the equipment you don't need a how to, and if you don't have the equipment you won't be able to do it anyway.
I looked to do it myself recently as the bits are for nothing. Unless your proficient with a welder I wouldn't bother.
It will definitely come off, just keep drilling the spot welds until they are all gone. Best to use a spot weld remover or blunt drill bit though so you don't go through both pieces.But unless you can spot weld it back on then I'd probably leave it there.
Ha ha...I've just hammerited mine as there was a few bits on it. when mine next goes in for any work I'll definitely get them to replace it!
pulling off the old one is the easy bit! unless you know what you are at refitting the new one, you will end you with badly fitting lights, wings and front bumper!
