Installation Notes:

KFV cases are riveted onto strips and require drilling and re-riveting for installation. It's important to note that older KFV locks have different connectors and cannot be replaced with newer gearboxes. When replacing gearboxes, ensure that the model is compatible, as early KFV models may have different rivet spacing.
