They can be installed on a stock baskset, but its not a fun process. You have to drill or grind off the rivets on the basket, get the new ones in and then have the basket rivited back together. I would just get a billetbasket and go that route. On those you just take out four bolts to change the cushions, much easier and they are a better basket anyway. If you want one of those majicmike, and Jeff at FAST have them at good prices.
