2014 CX-5 Taillight hardware part numbers?

My Mazda CX5 has a loose tail light due to having a the missing hardware that holds the tail light in place. The bolt is still present and connected to the tail light but the washer assembly or hardware is gone and I have no idea how it was lost. Do any of you guys happen to know the part number of what I’m describing? If it helps, the part I’m missing is actually located in side the car in between the plastic body cover and the exterior lift gate.
