Whatever works best in your situation. What you can do on a stock control arm, is use a 5/8" bolt, and a piece of 1" 3/16" wall DOM. I cut the tube to the right length, then cut a slot down the top of the tube wide enough to weld into (1/4" about) and drill a few holes farther back to plug weld the bolt to the inside of the tube. This is the easiest way to do it at home with limited tools. I like to make them on the lathe, but I realize not everyone has one.
