I run a stock / slightly modified d1 bumper on my 2002 and had it on my 2000 previously. 2003 of course is different again but will fit with some minor modifications.
Looks like a $500 truck to me not $2300
Not sure on the sliders but pretty sure not compatible.

99 to 2002 use a flat contoured glass headlamp with separate turn / marker lamps. Same headlight as a discovery 1.
2003 , 2004 use a euro style one piece plastic lense lamp .
Bumper changed for 2003 , 2004 as well but the bumper will still fit / line up to the frame horns.
Google / search some pictures??
