Hunting rack swivel shooting chairs

Thanks in advance for any advice or ideas. I bought this Tacoma about a month ago, and converted it into a predator hunting rig last weekend with the help of some friends that are very talented metal workers. We hammered this project out, rust removal, prep, primer, paint, clear coat; built, primed and painted the rack and installed these 5 lug tractor hubs on spindles, for future chair install. Does anyone have experience with mounting chairs on hubs that would be willing to give a brief explanation or share photos? My goal is to end up with shooting chairs with table / rests attached. Thanks again!! I am open to any suggestions.

We used the correct rim size and mount post with a seat on top. Removed the seats and stands when not hunting and used them as stools around the fire pit. Used 2 lug nuts to hold them n place.

Thanks. Sounds like a solid, simple plan.
