When you rebuild an american standard toilet (old style) the trip lever hole is bigger than what a universale trip lever will fit. I have not been able to find a good fix for this. Today I tried using a 3/4" thick aluminum square tubing that was 5/8" i.d. and fit the trip lever perfect but I had to grind it down to fit the toilet. I guess the trip lever hole in the toilet is about 11/16". Any one no a good fix?
