See attached photos and descriptions showing modifications needed for our mount to work with the newer Coleman 550 as stated on our site.
We put a 3/4 inch steel plate between bottom of frame and mounting bracket to level it. (Wood or stacked washers would work fine also) and u bolts around brush guard/winch bars to hold front/ top of bracket. Had to get 10m-1.5 x 50bolts as there were none originally in frame.Got everything at our local Ace. See pictures below.
