Reply to Midi fighter mod question

i want to add some line faders to a custom midi fighter project i am trying to make. I know you have to use 10k line faders but am having trouble finding them in aus. Anyone know of any good places to buy them that will get to australia cheap. Also i have a old djx 700 laying around i couldn't rob the faders off that could i.

I am adding some buttons as well is there anything else i need to add to the digital inputs to get them to work or just a straight wire in. I thought i read somewhere i need to add some resister or something.

Any help will be appreciated.
