When the men are loading the armored car into the truck bed the wooden planks they use as a ramp go from single boards to doubled-up boards and then back to single boards, presumably to make them easier for the actors to lift.
When the safe is first lowered down from the window, the riggers use two double ropes around the safe, but then when they show the ropes tearing and about to fail, it is just two single ropes.
At 22:29 into the show when Harry Green is putting money into the safe you can see a shadow of the boom mike on the top of the folding panel that is on Harry's left side.
