Context
When replacing the right rear seat belt retractor in a 2018 Ford Mustang equipped with the Coyote V8 engine, it's important to use the OEM part number FR3Z-54614B73-B for the best fit and reliability. This component is critical for passenger safety and should be inspected for wear, particularly the retractor mechanism and webbing for frays. Installation involves removing the rear seat and accessing the retractor, which may require specific tools. Note that while this part is interchangeable with models from 2015 to 2023, it’s essential to verify compatibility if sourcing from a junkyard, as minor variations may exist in mounting brackets or connector types across the years. Always check for proper function after installation to ensure safety compliance.
