I'm trying to change our kitchen faucet. Underneath the kitchen sink there is only about 4-5 inches between the back of the sink and the back wall. The faucet has a single mounting hole. I've tried for over an hour to try to remove the brass locknut without success with a pair of channel lock pliers. There isn't enough of room to swing any tool (if that makes sense). I've found special lock nut wrenches but i don't think they would help me because of the limited room i have. Is there anything i can get that would make my job a lot easier?
