The side panels are removable. They make an adapter side to put additional accessories on. Hopefully the side is not, in the correct position, and is able to be adjusted. If you have a Snapon guy, they usually will do it for you. Maybe a Snapon guy on here can chime in and explain how the sides can move. I don't know but I am interested in that same cart. I can get $300-400 hundred off (forgot exactly how much) on a yellow one. I figure if have to look it frequently then I should get a color I like. Yellow is not my color. Good luck. I was told that a 4 inch drawer, could be changed, to two 2 inch drawers. The Snapon guy offered to change that too, actually install it. Good luck.
