The Buick Regal and Century was offered with a few different motor and chassis configurations. There were many different gauge clusters for this vehicle, but only one will work in your car. Whether it had ABS or not, a supercharger, tachometer, column shift or floor shift all of these features mattered. The most common issue with these are failed display and odometer screens. Gas gauge or gas level issues are typically not a cluster problem, but a fuel sending unit issue. Provide us with your VIN and we are able to pair the correct refurbished cluster for your car.
