Crown Automotive 8122874K, 8122874K2, 8122874K3 Installation guide

Hello! I've reviewed the Assembly Instructions for the Crown Lock Cylinder, which is designed for specific Jeep models like the XJ, MJ, YJ, and CJ. The document details the installation process, especially noting the arm removal that might be needed for door applications on YJ and CJ models. I'm ready to answer your questions about this document.
What Jeep models are these lock cylinders designed for?

Do the lock cylinders function on doors of YJ and CJ models?

Who should perform the assembly?

The arm on the back of these lock cylinders are designed to work with 84/90 XJ

Cherokee, 86/90 MJ Comanche, 87/90 YJ (tailgate only), and 81/86 CJ-7,8 (tailgate

only). In order for these to function on the doors for YJ and CJ models the arm must

be removed from the OE lock cylinders and installed on the replacement cylinders.
