I have 3 helpful hints. 1) sand the cab halves mating surfaces on a large piece of sandpaper taped to a flat surface. This will true them for when they are glued together removing the gaps. 2) Removed the useless ceiling porting of the window glass piece to permit the side windows to adhere to the doors of the cab. 3) File down the upper perimeter of the assembled interior to help it fit into the body without splitting it apart.
