2 handle single spout with sprayer purchased around 2003-2004. It needs new cartridges as it drips. Looking online there seem to be a few that might fit. Some need a special wrench of some sort and some don't. If new cartridges solve it for another 10 or 12 years I will be old enough to not care. I am hoping to not have to buy the special wrench as the one I saw on the same website was around 60 bucks to never be used again. If I take off the spout faucet handles and chrome cover are there normally any numbers on the main body that are helpful?
