I'd keep an eye open in the parts section of our website..there are a few sellers who often are either parting out a 300D or know of some in junkyards. Usually they don't list the panels but might have them..I got mine from there. I can't tell for sure how much of a sound difference they make, although it is nice for catching oil leaks
