Just been out and measured it, the box is 40mm tall, 68mm wide and 80mm long.
The xr4x4's arb is 14mm the same diameter as the 3 door cosworth iirc, doing it this way opens up the options if you want to go thicker the 2wd saph cosworth is 16mm, 4wd is 18mm, granada cosworth is 21mm and Escort cosworth is 22mm
