Pat's Easy Change New Holland TC33d ballast box issue

[JerseyRay]

Recently purchased Pat's Easy Change category one for my New Holland TC33d. I installed it on my tractor and tried to attach my New Holland weighted ballast box. The problem I having is I cannot attach the box. Part of the box flares out to the side on the front right above where the box's pin's are. There is not enough clearance to hook on the Easy Change. Has anyone had a similar problem ?
