This is an 82-84 Firebird gauge cluster for V8 cars. This cluster has a cable driven 145 MPH speedo. These cars only came with 85MPH speedos from the factory so this cluster with a 145 MPH speedo would be a great upgrade for your car!!! It is an 82-84 style piece but will work for 1985 cars as well. The odometer shows about 23k miles.
