I've been running 3/4" chromoly heim joints on my steering for quite some time now. They just had 5/8" bolts with bushings inside. Well I decided to upgrade the bolts to 3/4". We decided to tap the knuckle to 3/4" thread with minimal loss to the knuckle strength. This also distributes the force on the bolt more evenly over more threads than just the nut. This also eliminates the slack in the steering which was due to the drivers' side tie rod bolt needing to be loose so the heim had room to work.
Of course the new bolt is too long. I'm just showing the difference in width.
Minimal loss of material from knuckle
