Body Hinge

Discuss body hinge process from car 3 --> car 4 --> car 4.5 --> car 5. 

Will need bragg to take on the car 3 --> car 4 role. Discuss mounting, linkages/rods, failures, manufacturing, and how lengths and locations were selected. 

We also should discuss the telescoping rod placements (though some of it has not been finalized for car 5)
