This ad is for a genuine GM Driver's Left LH Side Exhaust Manifold With Shield as shown on the pictures. I am not willing to sell just one of the two. They must go together. Manifold part number; 12600526 Shield part number: 12597917 Please before you place an order, use the GM catalog numbers I have provided above to check with the dealer or compare the pictures on this ad with the item you need to replace in order to make sure it is the item that will work for your Vehicle. The list of compatibilities above is just for reference. This item has never been installed. I received it in a master case, so I do not have the original packaging for this. It will still be boxed up professionally for shipping.
