Kuhns accumulator setup

Hi everyone, I'm setting up a used Kuhns 1534 accumulator behind a New holland Bc5060 baler. Can anyone post a picture of theirs up close on the bake chute and the hitch? I look at pictures online and some don't have the black tray on the accumulator like mine. I assume that just rests backwards on the "ramp"?
Also, I can't afford the corning kit right now for $700. Anyone modify or make their own? Anything I can do to help the unit on corners? Thanks guys
