Nice work on getting everything in place so neatly! Are you going to use those small batteries that you had before? If you do you could raise the board and put them underneath of it - I think it will still leave some sort of room for a mock interior too. Here's a suggestion: maybe you could also cover up the electonics and do the interior like from the dash up (similar to what I did for my covertible camaro and G35)- you might have to glue the door on and then they'll be able to see rthe mock interior through the windows.
