Track bar frame mount

[clemsonteg]

I am coming back to this now that I have redone part of my suspension. I am considering taking the rivets out of the current mount, installing some sort of spacer and remounting it to the frame with grade 8 bolts. Has anyone done this? My only concern is the force which would be applied to the bolts, especially considering the force will be applied 2-3" from the frame. I am thinking I could use a piece of rectangular tubing as the spacer.
