Boom.....
Here is the link to the mounting tabs/buttons
And in the process came across a pre-fab table that might save time.
Finally found them.
Never mind @waveslider found them. And that table is very nice!
Could always cut the middle out of the table and weld it back together.
The thought crossed my mind.
I'm torn between this kind of "removable table with bracket" concept and just doing a Tailgater Tire Table and calling it good. I was drawn to the mounting tabs/button and table concept because I need something easy to deploy/take down and the tire table (which I've used for a year or more now) might end up being the winner.
