After years of abuse from hours of Smash Bros(melee/brawl) playing my control sticks (and some C sticks for some unknown reason)on my Wavebirds are running quite loose. Does anyone have a link to a site that sells replacement stick parts.

Ive done the replacement myself before so doing it is not a problem. I've seen some websites that have universal PS2/XBOX/GC sticks but they say that you may need to custom fit the thumbstick part. I would like something that is specifically fits the GC controllers. Thanks all!
