You wont to change from right hand drive to left wich par do you need?
Go to a salvage yard and look for a duplicate car that is left
hand drive. Purchase this wrecked vehicle, minus the
engine?transmission, and use it as a donor car for parts. You are
going to need so many parts, that this is the only cost effective
way to accomplish this. Buying the necessary parts any other way
would be way too expensive. After you finish, put all excess parts
in the donor car and sell it back to the salvage yard.
