1998 Buick Regal Year Specific Sunroof Glass Panel. The sunroof is in good used condition. Measurements are 32 1/4" long and 18 3/4" wide. ***This sunroof came standard on Regal model year 1998 but please double check your measurements and compare to ours to ensure a perfect fit. Aftermarket sunroofs have become more popular over the last 10 years, if your sunroof switch looks like any in our last picture, you have an aftermarket sunroof system. This is why it is important to double check your measurements and bolt patterns to ensure a perfect fit. This sunroof will only fit on a 1998 Buick Regal. This glass panel was removed from a Regal 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 and clean the panels, especially the seals, AFTER they have been removed from the vehicle in an effort to identify any imperfections that may cause issues down the road. Seal issues cannot be identified until the sunroof has been removed from the vehicle. The sunroof comes read to bolt in. Please contact us with any questions that you may have.
