75 Dart Sport - What rear? What wheel pattern?

I have a good 9o's Magnum 360 engine and I've been looking for a project car for it. Came across a 75 Dart sport in nice original shape. (yet to see in person) It has a 225 with a three speed floor shift. Does anyone know what rear end it would have or if it's got the larger wheel bolt pattern or disc brakes standard maybe? Power brakes standard?
