Check out post #15. Mine was off too (maybe not quite as far as yours). I had to do a lot of massaging to the trunk pan (original) to get clearance for the front bar. I also used a bottle jack on each side to help push the cradle up to close the gap and then hold it in place while welding. My car also has original frame rails.
