Perhaps you already know this, but a used Defender 200tdi complete drivetrain (engine, transmission, transfer case, ancillaries) goes for about £1000 in the UK. If you are RHD then you can use the much more common Disco 200tdi, which goes for about £500 again including ancillaries, transmission and transfer case. All you gotta do is figure out how to get them here.
There are breakers in the UK that will ship to the USA.
