tracktion bar

im getting a lot of axel rap in the rear end of my rig. so im going to bild a tracktion bar for it. but i dont know it the angal of the bar should mach the angle of the drive line or if should be level with the truck? would if matter if it was offset to one side or should it be in the senter of the rear axel housing? one bar should be enuff?

im making it out of 1 1/4'' scegwal 80 steel pipe. with 3/4'' heim joints at each end. same stuff i made my steering out of.
