Traction bars

[BadBird]

I was going to make Cal-trac type traction bars for my 64 but looking at the setup tonight they will not work with the way the springs attach outside of the frame rails to a side bracket. Sooooooo I am looking at these. Any ideas or different approaches that are within spending limits? Say $100
