He means the Sticks.
You'd have to take the thing apart first, desolder it from the board and bend the 4 tabs under it without breaking all of them so you can get to the mess of insides. Then find your own springs that worked best. It's far more work than it's worth as they're designed to work with the ones int there. It can be done, it's just not a simple kind of deal.
Thankyou RDC
As you say it's a bit more complicated then I first thought. Might have a venture with an old controller just to see what it's like but my skills are limited.
