Asked for many times. I know URAS offers a kit (http://www.uras.com.au/yosonchi.html) but it is fairly expensive. Most shops should be able to do it if you supply all the body parts (bonnet, front fenders, lights, front bumper etc). Heres some pics of a guy in A.C.T who had it done, cost 11,000 (without all the other bodywork and paint, just for the front end conversion)
Some more pics of others

Would definitely do this if i had the money but dont try and be stingey on it, search for a thread by Adz(numbers) who bought a cheapo kit and got ripped off, paid close to 2 grand and they ran off with his money.
