Converting RHD to LHD is not that much of a problem,,,,, depending where you start from. If the car is already built, then you have issues with dash, shifter foot pedals, and rack and pinon. If you have a partial build it is easier. If you are ordering, then it is easiest of all. It just depends on where you are and what you want. Mine was a partial build of RHD. So switching wasn't all that dificult. Having things shipped from Australia was. So I outsourced all I could. Then you run into associated problems like bumpsteer and shifter problems, which I am wrestling with now. I don't mind spending the money, just don't want to be penny wise and pound foolish. So it takes a little while to figure these things out and get them implemented. All depends on your time frame and what you want. Do your research and then pull the trigger. It's a fun route no matter which route you take.
