All the other cutouts and bracket (e.g., to interface with the jack plate, to avoid stressing the differential, or to keep it in place) are just for alignment purposes, keeping it in the exact right spot and stopping it from falling off.



As shown in the pics, the 4x4 fits with a little clearance in between the exhaust pipes (M54, stock everything).
