My panhard bar on on both cars are from Pete & Jakes, mounted from drivers frame to two bolts holding the third member to the differential housing and two bolts holding the pinion shaft to the third member. I think the brackets to hold the heim are 1/4" - they are stout! The longer the bar the less lateral movement you get as the differential travels up & down, but the longer bar has more flex. In an easy swale where you're going straight there's not much force on the panhared bar, but consider a twisty hill country road where you're pushing the suspension to max G forces in a downhill S turn. You're putting the panhard bar in compression, then tension while going through a mid-turn dip that's trying to break the rear loose. Also, consider that as the differential travels up & down it moves fore & aft a bit in the arc of the parallel arms.Your panhard mounts are going to see those forces and have to be strong enough to put that movement into the bar flex, not the mount or the mounting bolt. Both ends of your bar rely only on the mounting bolt through the heim, in flex.

Your mount needs to be close coubled to the axle flange, and I would extend it above the axle tube an inch or so but I'd be very concerned with a single side mount that puts all of the force on the bolt through the heim. It needs to be supported on both sides so the bolt is only in shear. Same on the frame end, you need two plates welded to the frame solid to carry the heim. That existing frame mount won't last 50 miles,IMO. How about using a flat plate on the existingg axle mount, extending up with a second shorter flat plate welded to the tube spaced to fit the heim insert? Att the frame, makje a pair of triangle plates, rounded at the top, welded to the frame rail spaced for the heim insert. That would put your Grade 8 bolts in shear, and would be plenty stout!!
