Ok you can get a rhd front clip off hmotorsonline for around 500 bucks, You need to make sure it comes with brake and clutch cylinder and the steering rack

Other than that all you need is the fire wall and the dash the fender wells and everthing from there up is the same.

If you get the front clip it can be done for around 2500 to 3000 or at least thats what I would charge to do it thats if you supply the parts. If anyone try to charge you more then that its a rip off.
