These came out of a 2008 Reading/ ABC(American Box Company) van utility box.
The 3 drawer set was in the cabinet closest to the cab. That compartment is approximately 34 1/2 inches wide 13 inches deep.
The 2 shelfs came out of a 23 1/4 inche wide compartment. Which is the back cabinet.
I know they don't fit in a 2005 Reading box.
I don't know if they will fit other brands. They mount and lock in on the brackets in last picture.
Price is negotiable. Would like gone or they will go into scrap trailer.
