I ordered them through the local dealer. They are selling all the dash pieces I need for $320. They are giving me a discount since I bought the truck from them. I think the regular price was around $400. I do not know the part numbers. Your local dealer can look them up for you. Just tell them you are looking to trade out all the wood dash pieces in your Silverado with the brushed aluminum pieces from a Tahoe. You will also need the pieces that go around the air vents even though they are not the wood look they will not match the brushed aluminum pieces from the Tahoe. If you goto
Official Chevrolet Site | 2008 Cars, SUV's, and Trucks | Chevy you can find some pretty good pictures of the 2008 Tahoe with the brushed aluminum dash trim. Looks sweet compared to the wood look in our trucks!
