The #39 team picked stall #22. The 1st pit past the Start/Finish line. In front of Ryan is the 66 car which I believe is a start & park car, so he should have a clear exit out of the pits. The good news about being the 1st car past the start/finish line is there is a small gap behind his pitstall for the TV cameras, so he should have plenty of room to get in his pits even if Vickers is in front of Ryan who pits behind Ryan.
Both SHR cars shouldnt have to worry about entering their pits or being blocked coming out by races end.
