There has always been talk of using the manifolds from a 265 and reversing them so that the exhaust does dump from the front. I believe that the 305 may have the same type.
However in spite of all of these possible remedies I have yet to hear of anyone being successful without moving the steering box. I personally would not want to move the box but it does happen. There must be a lot more in the 'search' feature on the site.
