I decided that I'm going to build some traction bars for my truck. I know there's a few threads on this but I just have a few things to ask. How should I attach them to the rear axle, weld some brackets on? Also, which would be better to use, Johnny Joints or Heim joints? I'm thinking about using Johnny joints for my bars.

Also if anybody could post pictures of the bars they've built and possibly a list of materials and dimensions, that would be great!
