Here's a couple of pictures of what I came up with. Bolts on under the crossbar using the existing thumb screw knobs. I had a custom order for one of these that had a tray cut out of the left side for them to pour the nibbles in and just 1 nibble jar holder on the right side and 2 toolholders on the right side. I can text/email a picture of it if you're interested.
