This is what we see as the standard Panhard / Trackbar bracket. It has 3 mounting position options, 5.5", 6'5", & 7.5" from Axle center. However, these are cut to to fit the leading edge of your axle & made from 1/4" plate 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 miss alignment. 9/16" holes.
