'Measure twice cut once'. Before you start taking all the stuff off and adjusting the shelf heights, double check the total width of the 3 bins on the top to make sure they will fit between the support bars as they are wider at the top vs. the bottom. The bin on the left looks like it would be even with the vertical bars but the one on the right looks like it is pushed over and might over hang those 2 support bars. If all else fails, you could put the 2 heaviest ones on the bottom leaving the lighter one on top. The look won't be symmetrical but it would be safer when taking something heavy like that down that is above your head.
