383 into /6 dart?

how about the room around the power booster for the brakes, it looks to me like it could be a tight fit, I have just done some measurments of my own, and it seems tight. All the pictures I see none of the cars have a brake booster in them. Also is there a link someone can send on the tri-y's.
