Discovery 2003 facelift

My 1999 discovery 2 is in need of a new bumper thanks to an old dear in a micra , so i thought i would put on the 2003 lights and bumper while im at it.

Am i right in thinking that the bumper just goes straight on and i need to cut some metel away behind the lights? if so could anybody tell me which bits to cut. Also does anyone know a cheap place to buy lights and bumpers.

you could always try flee bay there is normally a guy on there selling the plans on how to do it and he is normally selling a set of lights as well.

I have noticed some lights have auto leveling, is this system total enclosed in the headlamp or would i need other bits?
