Yes they can be converted, best way to do so, is to buy a wrecked 7 seat kluger from auction, maybe pickles, you will have all the parts you need to convert it and it works out cheaper then buying from a wrecker. I have been looking into it for my kluger You will have to get a engineer's report , called a "VASS approval certificate" and update the details with vicroads or etc cost around $500 if you don't and you have a crash, kiss good by to your insurance
