Do you mean you're stuck not able to remove the faucet ring on the outside of the tower, per faucet? Or you're stuck removing the brass 1 1/16th shank nut on the back of the faucet, inside the tower?
The former I think you could wrap your faucet ring in a cloth and gently use pliers, but technically you don't need to remove the faucet from the shank to install new lines.
For the latter, I followed some advice I found here and used a dremel with a cut off wheel to cut a half inch section (maybe more) out of a a wrench, the kind with the round end...I'm giving that a terrible description unfortunately. Not the open ended regular wrench, but the almost socket like end.
Cut out a section and you can slide the now "c" shaped wrench end around the lines and over the nut, bob's your uncle.
