I have entered into at least the 3rd level of plumbing hell, starting with a simple "Honey Do" request to stop the hot water bathroom sink faucet from dripping. I am unable to reattach and correctly orient the handles for the right side. I am a total novice, and I observe there are only two orientations for the cartridge since in has two notches that correspond the notches on the flange (not sure if I am using the right word, see pics) Looking at the notches that will accept the tangs on the cartridge, it looks like the hot and cold are oriented differently. Hot water side is at about a 1 and 7 on the clock, while the cold is at about 10 and 4. I don't see any easy way to reorient the flanges. I have worked and worked with the hot side, and cannot get the correct orientation for turning on and off. Thanks.
