make your own mate, it will cost you about $10 tops and you can do what ever you like with it.
You can mount your gauges in there, make a custom holder for your cd's, wallet, mobile, loose change about anything really.
Be a little creative and im sure you will come up with plenty of ideas champ.
If all else fails then buy that bit of plastic from the dealer for $60 and be done with it :lol:
