NASCAR Sprint Cup Series Pit Stall Selections

Daytona International Speedway
Sprint Unlimited

(NASCAR Statistics)

How are pit stall's chosen? for the Sprint Unlimited, teams do a random draw, like the way the qualifying used to be, then teams choose their pit stalls. There is no qualifying for the Sprint Unlimited and the starting order is chosen by a fan vote.
If a car/driver has to go to the rear of the field before the start of the race due to driver change, backup car,
engine/transmission change, etc they do NOT lose their pit stall selection
