Default High Mount Lamp for 2005 STS

Some of the LEDs in my high mount lamp on my 2005 STS are out and I recently discovered the entire lamp assembly must be switched out. I've contacted the stealership and they are asking $250 for the assembly plus labor. I have found some OEM aftermarket high mount assemblys; however I would like an exact match to the factory mounted lamp assembly. The stealership would not provide a part number; when asked why the parts tech eluded to the fact the stealership did not want persons to purchase the parts online (guess it is bad for business). Anyhow, can anyone throw me a rope and provide a part number for this item. The following link is to an aftermarket version of the part I am after; however, I figured it may be a helpful visual reference for anyone interested in helping me out.

Thanks in advance.

Thats no aftermarket high mounted stoplight it's a ginuwine OEM accessory but if you want a red one keep checking ebay, they are on there quite often.
