Well for all those wondering if Quickjack will work for a 68-70 roadrunner, the answer is YES. Its pretty stable too, but I am going to use jacks stands just to be safe. One thing is I have frame connectors and I am using them as lift points, I don't know if it would work without them, not long enough. They have blocks that are made for pinch welds so you may be able to lift it that way without the frame connectors. I was surprised on how much room it gives, plenty for doing things without being squished. I'm satisfied with it. It took about 4 hours to set up but that was me taking a lot of breaks because my garage is so hot.
