This is what we see as the standard Panhard / Trackbar bracket. It has three 5/8 inch bolt holes with mounting positions at, 5.5", 6.5", & 7.5" from Axle center. They are cut to a 3" axle tube radius so they can be made to fit any tube diameter & made from 1/4" plate too and bent perfectly so you don't have to play with the grinder to make them fit! They have a reinforcement plate to weld in after you determine the correct height for your rig, if it ends up to be the low hole just cut off the excess. These are setup for a 2" ID so just about any heim will fit with minimal misalignment.
