Hello all im new the the mitsubishi world as of today, i bought a 2004 mit. lancer OZ rally edition. The question i have is that i want to install my after market stereo into it and i was trying to find the housing unit for the HU (or dash kit if you prefer) but i could not find one on any of the websites i was looking at (sonicelectronix, crutchfield, etc.) what i was wondering is: Do i actually NEED one for the car or does any single din aftermarket HU fit into it without one?

Thanks all!
