The one I have is not from Abbott or GS (another knock off), but I could probably photo an end piece as it's still off the car. But, it is essentially what I described. You could use a thick, hardened washer and probably eliminate concerns about longevity.
The rivets on the bar I have are 3/8"-10mm diameter. The rivet-nuts jake described are like these: https://www.mcmaster.com/rivet-nutsWhat kind of rivets should i use for the rear 2 bolts?
Also what size are the screws? will probably use some really thick ones anyway like 12mm or maybe even bigger...
Also the bars for the brace, are they hollow or solid core?
Post mechanical engineer notes:
The stiffness of the brace would be greatly increased by increasing the vertical dimension of the material vs. the horizontal dimension. Ex: increasing the width by a factor of two increases the stiffness by two times, but an increase in thickness by the same amount increases stiffness by eight times. We are somewhat height limited, so increasing height changes would be limited.
Another point: a square tube will have more stiffness than a comparable round tube. You'd be better off with a 1" square, 1/8" walled tube vs a 1" round, 1/8" round tube. Same rule if you use solid material with the lead going strongly to the square material. Since a square tube wold require no additional height and it adds stiffness, it's the way to go.
Lastly, the square tube would make the ends a breeze - drill through and you can mount. I'd probably put in a spacer of solid material to stiffen it and avoid crushing the tube, but it would still be far easier than making ends for the round bars.
