If someone has the ipac and optipac to give, i'd be shocked lol. Usually people buy what they are going to use. The joysticks, though might not be as hard, but the ones that you adjust from the top are kinda new and kinda pricey. You could just order the joysticks from groovygamegear.com. i think they are about 30, a piece. Might be a little more.
Good luck,
groovy~
