callieco, Thanks for the question on the American Standard Pivot rod kit. You do need to be careful when threading the nut into place, you should do so with your hand until you can ensure the threading is not cross threaded. Your American Standard Consumer Connection Team.
Mikeg325, You would need a new drain assembly and that part number is M653475-0020A for chrome. Sincerely, your American Standard Consumer Connection Team
You will need an American Standard pivot rod. I had the same issue, the generic version ball is too large to fit.
It's about 1/2 inch in diameter.

This particular pivot rod is no longer available through us. You can purchase the drain which will have the pivot rod in it if you would like. The complete drain number would be M953465-0020A.
