I have the same problem. Any luck on this Mike? I was told it was my pitman and Idler arms going bad, I also have a bad torsion mount, everything is being replaced this winter.
I am looking to do the same thing this winter. A friend of mine just did his 69SS with Eastwood Rust Encapsulator. Anyone here have experience with that?
I got a huge parking lot at work we can all meet at or you can all park your trucks in front of my house and hang out in my garage till my girl comes home and throws us all out.
