More or less Jim,
You'll need the following parts....
Bonnet (hood) + Grilles
Wings (just the metal) - reuse all the plastic
Bumper (with fogs) + grids (cant use the old ones)
Lights (with mounts)
Corner PDC sensors
Brackets to join wings to bumper.
Ideally, get the parts painted prior to fitting preferably (also less time off the road).
The new lights have a different single 12-pin plug, where old lights had four seperate plugs. All same colour coding. Cut off old plugs and join using bullets - then waterproof. See Zulu document on facelift headlights for exact details including, turn signal mapping (uses different colour coding). Fit the lights before the putting the bumper on.
You can use the old bonnet brackets, and bumper carrier, but remove the plastic shroud either side of the aircon fan (photos later).
New bumper is a tight fit - but once it clips in on the corners using the brackets, it all looks very tight. Had us in a panic at first !
I would say buying the parts new will be expensive, as even the lower grid costs $134 on its own !
You really need a donor car, flood damaged or rear ended. You should be able to find them in amongst the hens teeth

. Seriously though, just be patient - they do come up from time to time, and you need to be hard with the bargaining and dont show how desperate you are

- just pay the going rate for each part. As I said, I paid around $2000.
Good luck and happy hunting !
