Correct lugs for stock 18" wheels?




What size lugs do I need for a 2013 G550 Standard set of 18" wheels that came stock on the truck?
I am not sure if I need these:
Wheel Lug Bolt 14 X 20 X 1.5 mm
Part #: 000-990-53-07-M58
Or these: with 17mmm hex head...
Can anyone confirm for me? I won't have a chance to check in advance.
I am swapping out my 20" wheels and putting on the original 18" wheels that came on the 2013 G550.
I will later have 2 sets of 20" wheels up for sale (CHEAP to move fast). Both will have tires, one blizzaks the other scorpio all weathers (photos to come). Both have less than 9k mileage.
Thank you!
