Kohler Toilet Seats

My head 1-piece Kohler toilet (do not know the name) is one that has built-in anchors for the bolts. http://www.ehow.com/how_4802453_repairreplace-kohler-seat-anchor-bolts.html explains about the "$ 46 anchor bolt kit 84999.

What I want to know is if all the seats can be installed Kohler toilet on my 1-piece (of course, taking into account round vs. elongated)? Or are there specific toilet seats for Kohler toilets that have integrated anchors like mine?

Sometimes, depending on your model. I suggest going to a Kohler dealer and buy one designated for your model.
