Probably a custom job. There are many spreader type bars with fork mounts attached. Delta is one company.
They run about $150.
I made my own. I took three fork mounts ($10 each) and a piece of aluminum tubing (2x4 square tubing) and cut it to the width of my bed and then painted it. Then bolted the mounts to it. Cost about $40!
Of course, then I bought a Lefty fork,then a QR-20 so I gave to my brother in law.
