Aftermarket Manufacturer reproduction
the electrical connector on this regulator will only match the original connector that was supplied when the car was manufactured - If the car has had a GM replacement unit installed, the connector on the door harness would have been replaced with a different style & will not fit the reproduction regulator
Products may be labeled as fitting either the left or right side. The left or right side can be determined by your position while sitting in the car facing forward. Your left would be the left side and your right would be the right side.
