I have the hatch here for my KV-2, I just never got around to installing it... it'd only be for cosmetics, do you already have a hatch of your own? I don't really need mine :P
If you can manage to fit a speaker box in the front, you'll get excellent sound out of a KV. I have a Tamiya standard speaker and it's amazingly crisp and LOUD with the Clark.
Also, Cobra Commander logo, nice
