As others have said, you are stuck with the EATC unless you want to come up with your own "custom" idea.
I have 3 major types:
1. Inside the console
2. Ashtray (remove ashtray and put it in it's place, requires a lot of custom work)
3. In the EATC.. requires the most fab (mostly fiberglass fabrication)
If you do a search on the forum, you can find pictures of all 3 of these. NebraskaSHO has his in the ashtray if you want to PM him. I'm not sure if James (StLouisSHO) still has the sho with the head unit in the console. Try PM'ing LJRuddy for that.
