Been after some of them myself, If you fit the earlier '98-'02 td5 headlights (but not the indicators) they fit straight in no messing, I know of a 300tdi that has the newer headlights in (last of td5's) but you have to cut your front wings out, move your headlight mounting plates back (spot welded on), replace trim, rewire etc etc, it can be done as I have seen one but I don't think it will be an easy job!! If you do it send me some pictures and let me know how it went and I might do it to mine!!
