Hi lmnewcomb, Thank you for your question. The hot and cold sides of your faucet use the same cartridge. The 1/4 stop portion of the cartridge is placed to the back on the cold stem and to the front on the hot stem. Please use the attached parts breakdown to verify that your stem assemblies and 1/4 stops are positioned correctly. The cartridge position will be the same on a 4" center set or a widespread 2 handle faucet.
