Without a before and after shot it was difficult to figure out. I went out and eyeballed my 06. Yours is missing the gasket alright. Seriously though, I would think that Gm probably ordered that gasket material from someone else rather than manufacture it. But you never know. Is there any way to get a part number or the name of the manufacturer from your service department? Or possibly from GM? My guess is -- they buy it by the roll. Worse case scenario, IMHO, you could find a suitable sub and install it yourself. I agree it looks rather $hitty without it.
