Found the correct Danco replacement stems - 4Z-24H/C.
The package says "hot and cold stem for American Standard. I replaced the hot and cold stems, but the cold stem now turns the opposite way - backwards. Is there an adjustment on the stem to get it to turn t he other way?

I imagine they open turning counterclockwise. You can't adjust or change since the body threads are made that way. Did the stems have levers or knobs?

I imagine they open turning counterclockwise. You can't adjust or change since the body threads are made that way. Did the stems have levers or knobs?. No but they have stops. I think I figured it out though. The stop can be moved by pulling a small clip off the stem. I think that will change the direction of the handle and stem. Thanks!

These are not threaded stems, they are like Delta. Move the plastic stop around 180 degrees.
