I have the frame and body separated on my '67 'bu and I am trying to decide if I should bother stiffening the frame either by boxing or getting an elky frame. I know that the elky frame should stiffen the car up more than boxing my frame. Before I took it apart I was running pst front end and body bushings. The body bushings helped stiffen the feel pretty dramatically, but it still didn't feel as tight as a newer car. What are some experieces that some of you have had that have gone thru all this? TIA
