You need to take a picture so we can see what you are talking about...really hard to troubleshoot in the blind. It is a rare faucet that can be replaced directly with new. You almost always need to move a few things around. A lot of the people here don't prefer Kohler...their design of the day means that it is almost impossible to get parts locally when it needs them eventually. Their parts book looks like a phone book, so it is rare that anyone has parts and they have to be ordered.
