Hello everyone. The flange is cracked and the closet bolt will not stay in place. Was gonna install a repair kit on top of it but the flange is warped. It’s 3/8 inch high on the left side and a little less than 1/4 on the right side. Do I need to cut this out? With a repair kit I’d be about 1/2 inch off the floor which was is too tall for my toilet. Suggestions on a permanent repair? Thanks in advance.
