You mean to one like this.
I don't know your setup but I have changed mine..was not a huge job but did take a little bit of work as I had to take out the plastic bezelthing that the faucet is attached to.
Take those four screws out then you get behind it to remove the plastic nuts that hold on the faucet ( remove water lines first).
Unless yours is different..that I don't know.
Ones I have seen usually are mounted to a bezel like this which has to be removed is all.
