Tach on Dash?

Well i scored an awesome deal on a 5" sport comp w/shift and warning lights, and i was pondering mounting locations, i want to mount on the dash, but it gets a little tight up there on a Duster. Anyone have theirs mounted on the dash of their Duster or any other A body, i know it looks kinda big, and kinda obstructs the view, but this is going to be a street/strip car, slowly evolving to all race car eventually, any pics of what im thinking of doing would be great!
