To know the exact gear ratio of a specific 1979 Camaro RS, you'd need to:
* Check the Vehicle's Data Plate (or Build Sheet): This sticker (often located on the driver's side doorjamb) might list the axle ratio.
* Look at the Differential Tag: The differential itself usually has a tag indicating the gear ratio. You'll need to access the differential to see this.
* Check the Owner's Manual (if available): The owner's manual might specify the gear ratio.
Without more information about the specific car, it's impossible to state the rear-end gear ratio.
