How does this piece fit? I have the rear plastic panels withOUT speakers. The pics on their site don't show it in great detail. The shots from the rear look like the plastic panels are still intact and not cut, the shots from the front look like the plastic panels are slit and the bulkhead slides INTO the panels.

Also, does the panel just float or does it get attached? And has anybody actually passed NHRA tech with it? With a battery, nitrous bottle and fuel cell back there? How much access do you have to the rear compartment with the bulkhead in place? Enough to change a nitrous bottle or fill a fuel cell?

I'd like to cover mine with some thing carpet (speaker box carpet maybe) to make it blend in a bit better.
