First two, no problem, Hayden
You can get the carbontex drag washers from Fishhead.
You can get the spare handle from any Daiwa dealer - they just have to order it in for you. You also can look at an aftermarket handle like the Studio Ocean Mark or MC Works.
On your third request, all I can say is good luck. If you manage to find one, a lot of our members would love to know where you found it! The reality is that there is no stock or production available to overseas retailers outside of Japan at the moment.
