I was not able to attach the windshield or the arch piece on the back of the car on LDD, so they are sitting next to the car. They both attach just fine and without stress in real life, so there's no need to worry. You should be able to tell where they go by the pics, but if you need help, just ask in the comments.
There are two extra grille pieces on the LDD file that are unnecessary to build the car, but you can include in your model if you have them. The inventory includes only the necessary grilles that are included with 31006.
Please feel free to rate or comment on this or any of my other mocs. Thanks!
