It fit perfectly; the part was made for simple installation.

It does not fit with our Kohler one-piece K5172-0. The piece next to the lever does not fit into the hole. I am really disappointed as the one it came with looks cheap. In another home, I had the lever that I purchased from you on that Kohler.

proper replacement part, functions properly, appropriate availability

[This review was collected as part of a promotion.] It works like new. If you own one of these toilets DO NOT WASTE YOUR TIME BUYING ANYTHING ELSE,THEY DO NOT WORK.
