I have black sapphire pearl LS460 Cant get mudflaps from Lexus Aust for LS 460 .I put them on my previous LS430. Also, I would like to put towbar on LS 460 for say 1000 kg total weight... What advice is available ? I am holidaying in West coast USA for 3 weeks from 6/8/2011. ? LS460 mudflaps available there. Would LS600HL ones fit?
