I have a one piece kohler toilet and am trying to replace the seat. the problem is that one of the anchor screws will not come out of the toilet. I keep turning it (unscrewing it) but it appear to be stuck. how do I get it out? any suggestions? i've looked at the kohler site but have not foun any useful information.
i'm thinking of cutting the screw in order to pull it out.

any suggestions?
