The styling maybe different so get a bumper with the indicators and fogs already fitted.
Make sure the bumper infill is there as a mk2 is different.
As for the lights, a cheaper option is to try aliexpress for the lenses and swap them over, or get a scrap set of xenons with good lenses and swap them over, and no all mk1's dont have headlamp washers.
Thats all you need to changeover, and remember, your car your choice, dont worry what others think.
