I just did my bath remodel and the toilet got damaged during. It is cracked where the tank mounts up, the date in the tank shows what I think is a 1970 wall mount American Standard Glenwall. It is just a round bowl because of the small bath that it is in. Is there something that will bolt up in its place. The only thing I am finding are elongate which takes up about 3 more inches in this tiny room. Are the 4 bolt mounting pretty universal or not. So frustrated. Thanks Michael
