I was thinking about making my own Joysticks, am I missing any parts?

I will use existing gamepads for the boards that I can buy at EB Games or flee markets for $5. I plan to have my casing done by someone and buy parts from lizardlick.com.

Now in my shopping cart, I have:

-Sanwa OBSN-30, 30mm Push buttons
-Sanwa JLF-TP-8YT-SK Joysticks
-Sanwa LB-35 Ball Tops

Am I missing anything important besides wires?

Joystick harness and some quick disconnects.

Would these work for Harnesses: http://www.lizardlick.com/search.asp?keyword=harness&search.x=0&search.y=0&search=GO

What about these for Quick Connectors: http://www.lizardlick.com/search.asp?keyword=Quick&search.x=0&search.y=0&search=GO

If it's a JLF:

And I think both Sanwa and Seitmsu are .110 for the QDs.
