Instead of cutting the old bolts, I decided I would just replace the wax ring and put in new, break off bolts so the caps would fit. However, when I pulled off the toilet, I see the bolts were glued to stay up. The flange is broken in both bolt locations. I bought a replacement ring. It wouldn't go over the old ring like some videos show. (I might have pick up the wrong ring) Do I just need to remove the old ring by grinding or does it also require the pvc (or ABS) to but cut out. Also, I used silicon to hold up the new bolts so I could reseat the toilet. The bolts turn so I can't get them very tight. Is that bad? It is not leaking but I know this is not a long term situation. (btw - this is a 2nd floor condo)
