Hi Lee,
MB Models usually hold them in stock, but seems they've already sold
Before pulling the trigger on the YZ-2 parts, if you have a donor or can borrow a car to measure up, check the hubs. From memory I can't remember if the king pin is much thicker, which means you may need to modify the Tamiya wishbones. It may all fit perfect, but worth checking everything out first, especially the sizes of king pins
