I have a 2008.5 Mazdaspeed3 in the Sport Trim. Since I don't have a GPS module (that would be Grand Touring), I was wondering if I could replace the panel over the center vents with one that has a shelf? I figured there would be space behind the vents for a shelf that opens since you're supposed to be able to fit a GPS unit there anyways.

Does anyone know where I can find an aftermarket shelf that I could use to replace it with that matches the original dash? Also, do the Mazda3 and Mazdaspeed3 share the same dash trim?

Thanks a lot for the help. I've been looking all over but can't find it.
