It's a metra universal gooseneck mount.
I got it at
Circuit City
The trick is mount it low and then I also put rubber feet on the bottom of the radio face and the mount plate so it wouldn't rub on the dash. I've used this setup since I installed the radio and have been nothing but happy with it.
The only change I'm going the be making is I'm going to remote the mic to the center console.
Also if you haven't bought the remote kit yet, don't. You can order the nesting plate for the face for 5 bucks from the Yeasu parts department(i will look for the phone number, and the remote cable can be built with cat 5 and 2 6 pin RJ-25 connectors. I built my own remote mount kit for 30 buck with the mount. This would no different with a 8800 or 8900
