Most post-style aftermarket radios do fit the cutout just fine. I had mine mounted there originally until a leaky windshield gasket fried it, LOL.
It was still under warranty, so I opened it up on the kitchen table and let it dry out, then brought it back to Tweeter and played dumb that it simply wouldn't turn on, LOL. So they fixed it for free, and i bought a marine stereo waterproof box from Crutchfield and bolted it to the front of my center console and used that from now on. Worked beautiful.
