Hello TruckZor,
I bought mine from VanDevere Chevy, and Dal helped with the part #'s, but they aren't a site sponsor anymore as far as I can see. I would suggest doing a search for Chevy OEM parts online and just go with the cheapest you can find. Gandolph if you read this, you can show your sponsors what advertising here will do for them. You can buy just the front portion of the console and then just take it to a Big Stereo shop. They have the material to match the grain and color of the rest of the console. I do not have the LCD screen of my Nav unit mounted down on the console but Avalanche Rookie mounted his screen in that area and says he is very happy with the results. The only drawbacks with the mount I did was cutting away so much plastic that it weakened the top section with the clips. The clips snap into the Dash piece to hold it more securely. My console feels very secure but mostly this is due to bottom mount not the top.
I don't have the part#'s any longer and I'm sure it is different from year model to year model. I would suggest going to local dealer and ask to see break down. You will need the metal bracket for the bottom mounting point. You will need the Main front section of the console made out of plastic(it may come with the above mentioned metal bracket for mounting, I don't remember). You will need the plate that has the two cubby hole pockets. I also ordered the inside of the pocket for the top cubby hole but this was an accident because I knew I would be cutting out that area. I used a cage mount on my stereo to install it and then bought a face plate to hide the edges of the cage and where I trimmed away plastic. If your not comfortable making your cut out get a Stereo shop to do it. The charges for cutting and fabricating a front plate to exact OEM color and grain should be around $50 and certainly less than $100. One thing to consider is making a door out of the front section this would be a good place for trash or maybe even a CD Holder. The area is tight between the front plate and cup holders but I'm sure something could be designed. We want pictures when you finish.
