      Hi Charlie! Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.

      I'm glad to be of assistance! This will not fit your 2000 GMC Sierra. However, we do offer an exact fit BWD Tail Lamp Socket - Part No. PT153 for your vehicle online.
