I've done my Gen1, and the pics look identical. The only difference I can see the placement of the OnStar buttons which makes no difference.
One thing I will mention - you may find the LED "dims" differently. The one I had would dim slightly then go out abruptly rather than do a smooth fade. So I ended up using a Silver Star regular bulb for the front dome. I have warm LEDs for all the other positions. The color between the two is excellent, and it's still cooler than stock.
While I like the cool LED for license plate and backup lights, I'm not real keen on the "cold" look it gives to my interior.
