I would have thought it’d be compatible as I believe JL4 is for Active Break Control, but on RockAuto it does specify with or without JL4 on their rear assemblies.Does anyone know if a JL4 equipped rearend is compatible with my non JL4 rear? I might have to replace the entire assembly, and a yard is telling me that it's compatible. Just want to make sure it'll swap on with no issues or modifications.
