I lifted my 67 using a 4" Rancho kit. It rides pretty poorly so I dont recommend it. On the steering issue, I mounted a new style power box using 1/2" stands welded to the frame. I took a drag link off an 80s sub then shortened it and cut new threads in the lathe(dont remember how much). The manual drums after lifting were a joke so I switched to hydroboost and it has helped alot, but the drums still aren't as good as discs. I have a complete 8lug disk setup waiting for me to find a open knuckle d44.
