I live over here in Australia and I own a 2001 Hyundai Grandeur which looks exactly like the American branded XG 350. I would like to upgrade the grubby looking headlights to the mirror finished ones available on the 2004-2007 XG 350 models. I believe the enhancements made on the 2004-2007 models were strictly cosmetic. Can I safely assume these parts would fit my 2001 model? The body style is the same as mine! I also want to upgrade the steering wheel to the burlwood finished one,which was also not available in Australia. How much trouble would it be to take off the airbag,replace the steering wheel and put the airbag back on? Thanks for your help!
