Hi Barry,
I reached out to Thetford directly and they confirmed that the replacement water valve for your Aqua Magic Style II toilet model # 42050 is the 42049 which is our part # TH78SA. I'm having the website updated to show it fits your model toilet as well.

VAlve itself is a direct replacement fits as it should. But if you buy the "kit" with the replacement donut, the donut (gasket) fits neither the mid point sealing cup or the base gasket. Wrong shape for the base gasket and does not fit the permitters of the midpoint gasket. They have changed something.
