2002 Chevrolet Impala OEM Factory Year Specific Sunroof Glass. The sunroof is in good used condition. Measurements are 33 1/2" long and 21 1/4" wide. ***This sunroof came standard on Impala model year 2002 but please double check your measurements and compare to ours. Aftermarket sunroofs have become very popular over the last 10 years, if your sunroof switch looks like any in our last picture, you have an aftermarket, not OEM. This is why it is so important to double check your measurements. Also be wary of sellers claiming this sunroof will fit many other years in the Impala line, it will not, glass is the same size, bolt patterns are different. This glass panel was removed from an 2002 Impala that had a blown engine so there is no unseen damage on this panel as is found with a majority of sunroof glass panels that are removed from wrecked vehicles. Often times on a wrecked vehicle, the metal trim around the glass, under the seal, will incur slight bends which will make the panel leak soon after. We have been dealing in sunroof glass panels for 20 years now and only sell the panels that come through our shop that are off of vehicles that have not been in major accidents. We also 100% inspect the panels, especially the seals, for any imperfections that may cause issues down the road. The sunroof comes read to bolt in. Please contact us with any questions that you may have.
