We have granite counter tops and are replacing a cast iron sink with a stainless one. We bought a 33x22" sink (which is the size of the Cast iron) and because of the clips (which the cast iron doesn't use) it wont fit in the hole. We bought (online) a 31.5x20.5" sink which is the measurement of the hole but don't know if that will work either because the clips may not reach. We really need some help here.
A. What is the right size sink, and B. What do we do to get the right sink to fit? We are new at this so I don't know if I've done something wrong.
