Bluegill: The base is a piece of angle iron bolted to the rack with square tubes welded to except the uprights for the ends. I have a front and back end with two cross bars to hold it together. With the rack dismantled, just the angle iron base with the square tubing is on the atv. Can take pictures and send them or if you come to North Bay, I'm just south in the Powassan area and you can have a first hand look. John.
