$3,000 or best offer for both top and bottom. Bottom is 60" wide, 28" deep. Top box is about 5" shallower. Would cost around $12,000 to replace with today's current models.
Has a few scrapes and dents, but it is pretty spotless inside and out. I just took the entire box apart, and lubed all the slides, and cleaned everything inside and out. All the drawers open very smoothly. On the bottom box, I just installed a set of MAC's high end soft foam drawer liners (~$250). The top box has liners too, but the more conventional type. Located in Westchester, NY.
If you are concerned about the cost of picking up, and moving a box this big, I have had great success using the 5'X9' ramp trailers from UHaul. $26 for the day, and it's not too hard to load a box like this with the help of a come-along and a whole bunch of ratchet straps.
