You don't need the ears for the bolts, they do nothing.
I would think that the standard foam washer in the Fluidmaster or Korky tank rebuild kit would work.
I am looking for what apparently is an odd tank to bowl gasket as I have not been able to find it anywhere. I am hoping that someone here can tell what brand this toilet is (can't find a name anywhere) and where I might find this gasket.
Wow!! Thanks for the really fast response. I'll try the fluidmaster gasket and see if that will do it.
The standard American Standard recessed gasket "should" work, but I had a Briggs a couple of weeks ago that looked like that one, and because the toilet's recess is extra deep it would not seal ith the American Standard one.
